Forks from the 1990s and 2018s were never meant to be orphaned!
Even if a few stupid guys lied to us and tried to cut off all support.
We'll document every detail we can find, share all informations and build spare parts for you
— so you can keep riding.
Measure stanchion diameter using a caliper, in most cases that's all you need. Consult our public Forks ↔ Seals Chart — a reference we have created by reengineering with ~800 fork entries — to find your model and matching seal kit.
Do you ship worldwide?
Yes. We ship to all EU countries and internationally. Standard EU shipping takes 3–5 business days. International shipping takes 7–14 business days depending on destination. Tracking is included on all orders. See our Shipping & Delivery page for rates and details.
Where can I find/buy Marzocchi forks?
At the peak of its development, Marzocchi ranked among the largest manufacturers of suspension forks and likely released millions of products onto the global market. Every day, listings appear on your local eBay as well as on numerous local sales platforms — such as kleinanzeigen.de in Germany, willhaben.at in Austria, and many others.
The same applies to spare parts: collectors sell off their collections there, or private individuals clear out Marzocchi parts from their attics and garages.
Also have a look at forums and discussion groups. Facebook nowadays is a good point as there are some special Marzocchi groups - I guess this are the most active communities.
Are your seal kits OEM or aftermarket?
All our seal kits are manufactured to OEM specifications with same dimensions as the original Marzocchi parts using up to date manufacturing processes and materials. They are not Marzocchi-branded (Marzocchi nor Fox no longer manufactures these parts) but are dimensionally identical replacements. Some of the seals have received small improvements (metal celeton, lips, springs etc.).
I'm searching for a seal kit, but I can't find my fork model. What should I do?
That's simple : for the years 1989-2018 we have the following stanchions sizes : 24 / 26 / 28 / 30 / 32 / 35 / 38 and 40mm. For 30mm and 32mm there are 2 seal kits available. The difference is the outer dust seal which come in 'classic' (flanged) or 'm-arch' style (non-flanged).
You also can consult our public Forks ↗ Seals Chart — a reference we have created by reengineering with ~800 fork entries — to find your model and matching seal kit. We have been busy to list as many forks as possible, but for sure it is not 100%.
How can I find my fork's year?
The year is stamped in 2-digits in the inner bottom of the lowers. Take that number + 1 and you have the year.
Can I order by phone or email?
We currently only process orders through the online shop. If you have trouble placing an order, open a ticket and we will assist you.
How do I know my stanchion diameter?
The stanchion is the upper (inner) tube of the fork leg. Measure its outer diameter with a calliper. Common sizes for Marzocchi forks are 24mm, 26mm, 28mm, 30mm, 32mm, 35mm, 38mm and 40mm. The fork model spec sheet or the fork crown casting often states the diameter.
I installed a new seal kit but the fork is still leaking!
Bro, honestly : If you have done everything right, that's nearly impossible. Check your oil seals have the right side up - that's the most common reason for instant leaking after inserting new seals.
- Make sure you have used a proper oil seal insertion tool to vertically press the seal into its seat — if you don't, the metal skeleton will bend and the seal will leak. - If there is a washer under the seal make sure it is in place. - Did you check the security ring above the oil seal? it is correct in place? - Make sure you did not cut the seals lips during inserting the stanchions into the lowers with installed seals. - For some forks it is possible to press the dust seal after all has been mounted - that's the best way. - Also never-ever re-use a seal you have already pressed in, as it will be bent from taking it out.
As a Buyer : What can I do to make sure my sending arrives?
1. Check your address double in the order / invoice. 2. Make sure someone is at home OR add a note for your shipping provider! 3. In case it did not arrive after a few days contact your local post services and ask for it. In most cases it will be stored and you have to pick it up.
How to identify my Marzocchi fork?
1. Go and measure your stanchions diameter. 2. Identify data from the stickers, in most cases you'll get forks name and model. 3. Find the 2-digit year in the lowers bottom inside to get the year and count +1. 4. Search my documentation repository https://public-repository.org/, compare crown geometry, top / bottom dials. 5. Find and compare an exploded drawing with your disassembled fork parts to get a close match. 6. Make some pictures and post them to Marzocchi groups like the one @ Facebook. ther users like to help you out.
HELP! It's leaking!!! There is an oil film on the stanchions!!! Seals are bad!!
Bro, sorry to say, but you did not understand MTB Suspension Sealing. 🤙
A MTB seal is not a Hydraulic Seal running 300bar oil pressure. It is a well constructed seal with multiple lips and a metal sceleton to seal air & oil pressure up to ~10 bar with less friction! Less friction alows easy movement of fork in low level compression/decompression - the very important smart moves to make suspension riding direct and sensitive. Stanchions have a fine, defined surface not damaging the seal lips and having oil pockets to keep frictions low and avoiod wearing off the stanchions coating.
But if it is dripping oil, than you have a real problem.🫵
Do seal kits include dust wipers?
Yes, all our kits include both 2 inner oil seals and 2 outer dust wipers (also called dust seals or scrapers). All kits also include a SAG ring. Kit contents are listed on each product page.
Where can I find Marzocchi documentation?
We maintain a public Marzocchi Documentation Repository with service manuals, exploded drawings, parts catalogs, period advertisements and posters — the largest collection online. Browse it at public-repository.org.
Same documents but with more Part lists, active maintained with better Search is the Docs Section here.
What's the best way to take care of my fork?
After every bike ride, rinse off the dirt using a garden hose, without applying pressure. Compress the fork a few times and remove the small ring of dirt with an oiled cloth; repeat this process 2-3 times. Regulary check air pressure and oil leve!
What happens to customers being rude, trying to sell me bullshit or trying trick me?
They're out. No more support. Will be black listed. Go your way.
We (hopefully) share the same passion and for sure we can talk about everything. Means we can find a solution for every problem. Seller and buyer are on the same level! If you think you are king of the road, having bad social communications, talking bullshit you are out - very easy & simple.
What Seal Kit Sizes are available for older Marzocchi Forks?
=> 24m, 26mm, 30mm, 32mm 35mm, 38mm, 40mm. Each seal kit has 2 oil & 2 dust seals.
30 and 32mm have each 2 variants in outer dust seal : classic style flanged (with edge aournd) and m-arch. Marzocchi made also 28mm seal kits. We don't mad them, as there is almost no requests.
What is your return policy?
Unused, unopened parts can be returned within 30 days of delivery. Open a ticket including the order number & date of purchase.
Custom productions we don't take back as these have been arranged for you only. Sorry.
Return shipping costs are the buyer's responsibility unless the item was wrongly sold by us or defective. We have the right to correct our order as usual, if we failed in something.
Usually we have an open ear for customers' requests. Be smart.
Why are your prices so high?
They are not. What I'm doing is low quantity productions, often 1-5 parts in CNC, may be 20-40 for a fut nut or some n * 100' in seals. This is very costs intensive. Most of us are used to have everything cheap, but that is mecause of mass production. I'm for sure not Amazon, selling millions of parts and sponsoring shipping with the overmoney they earn from cloud business AWS.
Why shipping costs are so high?
They are not. All shipping is standard DHL costs as I don't get discount for my low number of sendings. And all sendings need to be shipped insured & tracked or users getting mad. You can check costs in the net yourself at DHL.de, it is all about shipping product 2kg 'Paket'.
Why are you doing all this things about Marzocchi?
Because I can do it and I like to do it. If you have a nice idea : Just do it.
What Marzocchi fork are you riding?
I started with a silver XC600 and rode it many years. I also had bikes with red XC700, red DH3, orange Z1 1997 100, orange Z1 BAM 130 1999, Shiver DC 2002, 66 and 888. My daily Verlicchi Sintesi Bromont still has the Z1 BAM 130 mounted.
Why some of your seals are now gray instead of black?
Some kind of product evolution. I changed 30mm seals to better XNBR material and like to have some colour change as most of seals still are black. I can't use green because of SKF, blue is known to be very bad because of RWC/Enduro silicon seals, red is bad for forks to use.
Are XNBR seals better than standard NBR seals?
Yes. XNBR (carboxylated nitrile) seals do have meaningful advantages over standard NBR for suspension fork use — mainly better abrasion resistance, advanced UV protection and improved tensile strength, since the carboxyl groups create additional cross-linking in the rubber matrix. For a fork that's constantly cycling under contamination, that abrasion resistance translates to longer seal life.
I have a cool retro/vintage bike project and need some support. I like to discuss with other Marzocchi lovers.
Have a look at forums and discussion groups.👀 Facebook nowadays is a good point as there are some special Marzocchi groups - I guess this are the most active communities.
There are other forums as well like the well known RetroBike, also check local forums in your country.
I'm a huge Marzocchi MONSTER 40mm fork fan. Where can I found spare parts, other Marzocchi fan's and lovers?
The Marzocchi MONSTER Facebook group nowadays is a good point - I guess this is one of the most active communitiy online. And there are more Marzocchi groups.
I'm a huge Marzocchi SHIVER DC USD 35mm fork fan! Where can I found spare parts, Marzocchi fan's and lovers?
The Marzocchi SHIVER DC Facebook group nowadays is a good point - I guess this is one of the most active communitiy online. And there are more Marzocchi groups.
Why did you choose this website schema layout with the black header and the orange coloured styles?
One of the most important elements in Marzocchi history is the orange Marzocchi Bomber Z1 from 1997, when Marzocchi with all it's expertise in moto suspension started to rule the MTB suspension market. This orange Bomber Z1 is still one of my favourites and one of my most supported Marzocchi forks!🫵
Where to start best in disassembling a Marzocchi Bomber fork?
If it has footnuts start there 1st and loose the screws - do not unscrew complete as oil might come out.
Hello,
my sending has still not arrived. It take too long. I need it so urgent. Tracking shows it does not move. Can you call DHL and escalate??
Bro, what do you think we can do in detail?
Phoning someone at DHL, someone between here and your country, and this persons stands up from his desk and is working through 1000's of containers and millions of packages on plane, truck or ship to find your extraordanary important mega parcel, rushes to a car and drove it to you??
I'm sorry, but there is absolute nothing we can do than waiting for this process in delivering this parcel.
I know, time is money, your kid is awaiting birthday, your bike needs to be repaired and we all don't like to wait. Your package is in the system. It will arrive at some time, 99,5% of all my packages have arrived, but sometimes it simply takes a little longer for many reasons. Please take it more easy.
Check tracking again using DHL.de, also check the local tracking for your company.
We are not Amazon having a shipping system financed by AWS Cloudn Computing, having an own local shipment system, pressing people to work for very low money.
I'm searching for a part!?
Send in all details like fork model name + year, most important a picture of the fork and the part you need. If it is about a part which is missing, try to find a picture in the net from other forks to show me. I can't do this for you, sorry.
What's the best way to care my suspension fork in daily rides?
The best way to care your suspension fork is to clean after riding, especialy when doing dusty/rainy rides. Compress the fork a view times, it will create some kind of mud ring on the stanchions, take an oily towel and take this mud ring off, do it again and you are fine. And of course do some proper service and you will have much fun with your Marzocchi suspension fork.
Me personaly at home we have a garden hose at our bicycle stands, comming home from a ride we spray the bike a little to eliminate the mud as long as it is soft. No soap, no freaky cleaning/de-greasing stuff no hard pressure. And at some time we oil a little, we don't use any extraordenary oil/grease products - that's stupid marketing. That worked perfect for more than 40 years as it best.

Damping, spring and adjustment systems explained in Marzocchi's own words, from the
original catalogs.
AER
Air spring in a closed cartridge: low pressure, negative spring for coil-like plushness, light weight.
Air that makes you fly. The AER system performs better than any other system on the market. Countless reviews and tests agree with us! The low pressure required keeps the seals sliding smoothly on the surface with no friction at all. A negative spring offers plushness you would expect from a coil right from the beginning of the travel. Furthermore, the fixed piston in the closed cartridge helps to reduce weight since less oil is needed in the entire system. Catalog 2013 - 2013_Marzocchi_Catalog.pdf p.11
ATA
Air Travel Adjust integrates a dual rate air spring to simulate a coil spring compression ...
The Air Travel Adjust integrates a dual rate air spring to simulate a coil spring compression curve as well as 40 mm of infinate travel adjustment. Use the Schrader air valve on top of the stroke to perfectly tune the positive and negative air chambers. At the bottom of the leg, a second Schrader air valve is used to modify the progression curve and to control the bottom-out. Catalog 2008 - 2008_OE_BOOK_2.22_Italy.pdf
The Air Travel Adjust integrates a dual rate air spring to create the most coil spring alike compression curve and a super smooth 40 mm infinite travel adjustment. Using one Schrader air valve on the top of the stroke for a perfect tuning of the positive and the negative air chambers. At the bottom of the leg a second Schrader air valve allow to modify the progression curve and to control the bottom-out. OE Book 2008 Italy - 2008_OE_BOOK_2.22_Italy.pdf p.3
The ATA (Air Travel Adjust) is a dual air spring. It has two air chambers that control the beginning and end stroke of the fork. The ATA system allows to adjust the pressure of the positive air chamber. The negative chamber balances in an automatic way . Air pressure values will vary depending on the rider, terrain, preferred travel positions and personal preferences. On the 55, 66 and 888, the lower air valve is the PAR (Progressive Air Resistance) chamber. PAR is to adjust the progression of the spring rate and control bottom-out. The PAR valve is on the lower part of the fork leg and is protected by a red protection cover. The rotation of the Silver-coloured ATA knob installed on top of the fork leg, allows adjusting the stroke and the height of the fork in an infinite number of positions within a range of 40 mm. Catalog 2009 - 2009_Marzocchi_Catalog.pdf p.3
ATA stands for “Air Travel Adjust” and it's a totally new air system for 2007! The all new ATA air system breaks down the performance requirements that's always held back today's typical air systems. To accomplish this, we've separated both the top and bottom air chambers to be independently controlled and adjusted for amazing small bump sensitivity with precision tuning bottom out control. Why separate the two chambers? With single air chamber designs, the job of controlling both the positive and negative air transfer, while providing bottom out pregressivity, is an impossible task. That's why standard air systems are either too harsh or too soft and overall performance is compromised. With the all new ATA air system with the Progressive Air Resistance Chamber, both the top and bottom chambers can be easily & precisely adjusted delivering unheard of performance in both the initial feel and at the end of the stroke progressiveness. The 2007 ATA system delivers true coil like feel with incredible small bump sensitivity while having the progressive compression feel just like a coil fork. The main air chamber can be preloaded to adjust for SAG and initial small bump sensitivity. The bottom PAR chamber exactly adjusts where you want the end of the travel progressiveness to kick in controlling bottom out. Both chambers can be easily adjusted via external schraeder air valves located at the top and bottom of the fork legs. ATA also has that added bonus of 40mm of travel adjustment. By turning a top mounted knob, 40mm of travel can be easily changed allowing for the perfect front and rear suspension set-up. ATA can also be used to reduce the front end height making steep climbs easier (like ETA) by repositioning your body forward. Catalog 2007 - 2007_Marzocchi_Catalog_-_2007CAT-INTL.pdf p.4
ATA2
Simplified ATA: dual-rate air spring with 40 mm travel adjust, set with a single air valve.
ATA2 is the simplifi ed version of ATA. The Air Travel Adjust 2 futures an integrated dual rate air spring as well as 40 mm of infi nite travel adjustment. This no-compromise Marzocchi technology uses only one air valve to control the spring rate at the top of the stroke. Catalog 2008

C2R2
High- and low-speed adjustment for both compression and rebound, with a changeable shim stack.
With the C2R2 system, every rider will be able to find the perfect setting with the High and Low speed control for both compression and rebound with the option of self-tuning compression shims by easily removing the stack from the top of the right stanchion tube. A revolutionary design that allows riders to customize the setting for their personal riding style and skills, controlling the mid compression speed without the need of disassembling the complete fork or to bleed the oil cartridge. This works thanks to a three way oil flow circuit in the compression unit: a main circuit for the low speed damping controlled by a needle, and two different concentric circuits on the piston controlled by the shim stack. The first works on the mid speed compression and is managed by the flex of the shims, the second, for the high speed, moves the complete stack away allowing the oil to flow with minimum resistance. High speed can be tuned with the outer knob on the top of the right stanchion, preloading the spring that keeps the stack in position. Mid compression speed is also tunable by changing the shim thickness and controlling the progression between high and low speed damping. Catalog 2014 - 2014_Marzocchi_MTB_Catalog.pdf p.5
CR
Cartridge with adjustable low-speed compression and rebound; high speed tunable by shim stack.
More than what the majority of the riders need, the CR cartridge offers the control of the rebound and compression low speed keeping the suspension smooth and the tiers glued to ground, no matter the riding style or the terrain you are riding on. Not enough? The high speed compression can be tuned by upgrading to a custom shim stack: pure motorcycle technology! Catalog 2014 - 2014_Marzocchi_MTB_Catalog.pdf p.5
CV
Compression Valve: easy external compression adjustment, the evolution of SSVF.
The CV is the next level of the super reliable SSVF. The new CV is an easy to use compression adjustment to control the rate of compression and keeping the wheel sticking to the ground in all riding condition. Catalog 2008

DBC
DBC
Dynamic Bleed Cartridge: hybrid of open bath and sealed cartridge, coil-sprung reservoir.
Hybrid Technology: The Dynamic Bleed Cartridge is the most efficient riding control solution, which takes all the advantages of the most popular damping systems on the market: open bath and sealed cartridge. Based on a hybrid system, the DBC cartridge is a low pressure system with a compensation reservoir controlled by a coil spring instead of an air pressurized chamber. The oil will flow through two different circuits that, in the case of extreme riding, will allow the fluid to rush out the cartridge when the system gets under too high pressure. The oil will then be sucked by the cartridge inside again through a one way seal avoiding air to get mixed with the fluid, keeping the sliders always lubricated and each single damping tuning step effective and consistent in the roughest riding sessions. Catalog 2014 - 2014_Marzocchi_MTB_Catalog.pdf p.5
Doppio Air
Positive and negative air springs set separately, plus a valve for the progression.
Our positive and negative air spring system is brand new and was totally redesigned to be more durable and adjustable. It can be tuned to work for heavy weights and the fl yweight riders. Both the positive and negative valves can be adjusted separately to make your fork subtle or firm off the top of the stroke. It also has a new air valve (on the bottom) that features a progression adjustment. What this does is increase bottom out resistance without affecting the initial subtleness of the fork's travel. All of these adjustments can be found on our SL suspension fork models. Catalog 2005 - 2005_Marzocchi_Catalog.pdf p.6
ECC
ECC
Extension Control Cartridge: 5-click rebound lock-down, keeps the fork low for climbing.
Extension control cartridge ECC5 "extension control cartridge" is a 5-clicker lock-down system that gives the rider greater control over the feel and position of the suspension. Extension control functions as a rebound lock-out system so when the ECC is in the full open position, the rebound speed is fast and ready to react to high-speed descents and rocky terrain. As the ECC clicker is turned in to setting 3 or 4, rebound speed becomes progressively slower until you've reached the 5th position where ECC completely locks out the rebound and the suspension stays compressed. Extension control functions to reduce the front-end ride height making steep climbs easier by shifting the rider's weight forward and eliminating the "hill climb wheelie". The middle settings are great for fast race start sprints or climbing rocky up hills where suspension action is still needed, but without excessive bobbing. ECC5 can only be found on "doppio air" fork models. Catalog 2004 - 2004_Marzocchi_Catalog_-_2004CAT.pdf p.9
ETA
Extension Travel Adjust: a lever keeps the fork compressed for climbing, 25 mm stay active.
ETA is one of the most well-known and useful features developed by Marzocchi. The Extension Travel Adjustment keeps the fork compressed for easy climbing by simply turning the lever while maintaining 25 mm of active travel. Catalog 2008
ETA is one of the most popular and effective features developed by Marzocchi. The Extension Travel Adjustment will keep the fork compressed for easy climbing by simply turning the lever and always have 25 mm of travel. This climbing feature is a must for long travel forks. OE Book 2008 Italy - 2008_OE_BOOK_2.22_Italy.pdf p.3
ETA is the most widely used travel adjustment feature today. No other fork on the market today offers such an easy on-the-fly axle to crown adjustment like the ETA system. With a simple turn of a top mounted CNC knob, the fork's travel can be reduced by the rider precompressing the fork or simply settling in as you ride. For example, climbing on a 160mm travel fork pushes your body position back making it harder to get over the front of the bike for better and more comfortable pedaling efficiency. With ETA, the fork's length can be reduced down to 100mm (more or less) bringing your body position back over the front of your bike so you don't feel like your climbing on a chopper. For soaking up the small bumps while the ETA is activated, 30mm of travel remains no matter where you are in the travel, and when you reach the top of your climb, flick the knob and your fork returns to its full travel amount. Catalog 2007 - 2007_Marzocchi_Catalog_-_2007CAT-INTL.pdf p.4
Extension travel adjust ETA, derived from our ECC concept, locks the rebound of the fork and allows the fork to stay locked down in the compressed position while still providing 30mm of travel. Flip the ETA lever to the "on" position while climbing a steep section and you‚ll immediately notice the more advantageous climbing position giving you better traction with less wheel lift. Use it on fast fire road sections to hammer out of the saddle without unnecessary fork bob while 30mm of travel still takes the harshness out of riding while locked-out. ETA is an instant and usable travel reduction system which offers you on-the-trail advantages that will benefit you every time you ride. Catalog 2004 - 2004_Marzocchi_Catalog_-_2004CAT.pdf p.9
HSCV
HSCV
High Speed Compression Valve: motocross-style shim stack against harsh bottoming.
We are continually refining our High Speed Compression Valve (HSCV) damping. Last year, we adapted HSCV to the most talked-about new fork, the 888R. The HSCV cartridges in the 888R are as close as you can get to a motocross cartridge in a mountain bike fork without the additional weight of a full-on motocross cartridge. The HSCV regulates oil flowing through the bottom of the cartridge via wafer thin shims and a uniquely designed valve. As the fork compresses and oil starts flowing through the valve, the shims flex according to impact, speed, force, rider weight, etc; compression damping is instantly and automatically adjusted. This means when you whack a sharp-edge bump or land a drop nose-down, the HSCV works to eliminate harsh bottoming and loss of control, which lets you stick technical landings and prepare for the next drop. Catalog 2005 - 2005_Marzocchi_Catalog.pdf p.5
We've completely retuned the High Speed Compression Valve settings for 2003 increasing damping control under big bump situations. In today's fast and furious extreme riding revolution, going big is the common place and damping technology needs to be on the forefront of design. That's why every cartridge style fork we make utilizes our sophisticated motocross derived shim stack style "HSCV" technology. The HSCV regulates the oil flowing through the bottom of the cartridge via wafer thin shims and a uniquely designed valve. As the fork compresses and oil starts flowing through the valve, according to impact, speed, force, rider weight, etc; compression damping is instantly and automatically adjusted. This means when you whack a sharp-edge bump or land a drop nose down, the HSCV works to eliminate harsh bottoming and loss of control. HSCV system is used in all of our cartridge style forks providing the perfect damping balance that results from the HSCV cartridge being submerged in a total oil environment completely separating rebound, low speed compression, and of course high-speed compression damping. This is another example of Marzocchi's technological might and a 53 year heritage in suspension design. Why would you accept any other design? Catalog 2003 - 2003_Marzocchi_Catalog.pdf p.4
LCR
Adjustable low-speed compression and rebound plus full lock-out; open bath, cartridge weight.
It's the ideal combination between motorcycle technology and XC competition needs. Smooth damping, reliable and low maintenance as an open bath system but light weight as a sealed cartridge at the same time. Low speed compression and rebound can be adjusted by turning the knobs, both with a plus: the high speed rebound can be tuned by upgrading to a custom shim stack and the compression can be fully locked to challenge each climb! The internal blow-off valve will always keep the system safe also when you accidentally hit the trail forgetting to unlock the fork. Catalog 2014 - 2014_Marzocchi_MTB_Catalog.pdf p.5
Lock-out
LO cartridge: adjustable compression that locks the fork (20 mm left), remote on some models.
The LO cartridge allows adjusting compression damping. The CLOSE position allows locking the fork (by keeping a 20 mm stroke), making steep climbs easier. In some models, the LO system can be activated by means of the remote control on the handlebar. Catalog 2009 - 2009_Marzocchi_Catalog.pdf p.3

Open Bath
Open Bath
Both legs run in oil that lubricates, cools and damps — the heart of Marzocchi forks.
Open Bath Damping is the heart of our Marzocchi technology. Damping can be described in a multitude of ways but simply put, quality damping means greater rider comfort and control. Marzocchi's technology incorporates 53 years of suspension development where performance is paramount. No one else has our heritage when it comes to suspension development. Our technical philosophy lets our internal design take the guesswork out of complicated and confusing settings. After all, who wants to spend the time and has the skill to constantly be fine tuning their fork according to varying trail conditions. Using our sophisticated Speed Sensitive Valve technology, we've designed our damping systems to automatically provide the right amount of shock absorption. It all relates to how hard and fast you encounter impacts. The slower the fork compresses the less amount of damping is needed. The faster and harder the fork compresses the more damping is required to absorb the force and resist bottoming out. By flowing oil through a series of circuits or valves, damping can be varied automatically, taking the guesswork out of complicated adjustments. The Open Bath component of our design technology is pure and simple. Oil is the best damping element and that's why it's used throughout the suspension world. Marzocchi's "Open Bath" technology functions in three distinct ways; first the oil is used as a lubricant, secondly it's a coolant, and thirdly oil is a damper. Marzocchi's "Open Bath" damping technology has trickled down from our motocross division and our experience has taught us that it's the only design that provides superior performance and long-term durability. Our "Open Bath" system is used in both fork legs, some of our competitors use single sided system where oil is used strictly as a damping fluid (hatch back damping concept). Since suspension forks need to rapidly telescope, moving up and down thousands of times a ride, bushings should be coated in a bath of oil allowing friction free movement. The only deign that truly accomplishes stictionless performance is Marzocchi's proven "Open Bath" technology. Since oil completely bathes the internal bushings and cartridges all the moving parts glide smoothly, eliminating friction that causes forks to feel harsh and unresponsive. When friction is dramatically reduced or eliminated the life expectancy of internal parts like bushings, seals, and dampers are greatly extended. That's where the center of the legendary Bomber Performance comes from. Don't settle for anything less than Marzocchi's "Open Bath" technology. Catalog 2003 - 2003_Marzocchi_Catalog.pdf p.4
Marzocchi's legendary Open Bath Design dates to even before Marzocchi's inception in1949 when the original Marzocchi brothers insisted that their Ducati suspension designs only utilize Open Bath Systems. Not much has changed since the early days and we still insist that all our high-end performance designs operate around our Open Bath Technology. If you look back at our competitors, they have been all over the board in their technology offerings. At times, it is quite comical to read their old advertisements, touting each year's technology as the one that would revolutionize the MTB world. When the others were spewing buzz words and focusing on advertising campaigns, we were fine-tuning our proven Open Bath Technology, delivering continual high-end performance that has since become the benchmark for others to dream about. For 2005, we introduce the largest advancement in our MTB Open Bath technology. Once again by trickling down an amazing damping system developed in our Supercross Moto Division, our new ICON Damping System is born. Based on a closed damping cartridge, it uses a unique bladder rubber system submerged in a bath of oil. Catalog 2005 - 2005_Marzocchi_Catalog.pdf p.5

It is the leading-edge Open Bath technology by Marzocchi. The RC3 damping system ensures the maximum freedom of adjustment for a free and performing way of riding. The rebound control can be adjusted by means of the black-coloured knob that is installed on the top. The Position Sensitive Compression system allows automatic bottoming control at high and low speeds by means of the compression adjustment red-coloured knob, which is installed in the lower part of the fork leg. By means of the VA adjuster (installed in the RC3 cartridges for 888), every rider can adjust the air volume inside the fork by simply turning the VA knob. The variation of the volume inside the fork is the same as a virtual modification of oil levels. By simply rotating the adjuster ring you can reduce the air volume, this achieving an increased progressiveness equivalent to an increase in the internal oil volume. Catalog 2009 - 2009_Marzocchi_Catalog.pdf p.3
RCV
Rebound Compression Valve: external rebound (black) and compression (red) adjusters.
The RCV (Rebound Compression Valve) is the evolution of the wellproven SSVF Open Bath systems. The RV system controls the rebound speed. If you correctly calibrate the black-coloured adjuster on the lower part of the fork leg, you can keep the wheel on contact with the terrain in all riding conditions. The CV system controls the compression speed. The red-coloured knob on the lower part of the fork leg adjusts the compression. Catalog 2009 - 2009_Marzocchi_Catalog.pdf p.3

SSV
SSV
Speed Sensitive Valving: five damping circuits per leg that adapt to impact speed.
SSV (Speed Sensitive Valving) is our simple yet sophisticated way to provide consistent fadefree damping performance. Our SSV system uses five damping circuits per leg to instantly deliver incredible damping comfort and control. These valves operate in the compression and rebound phase allowing varying amounts of oil to flow through the system according to force and speed of impact. SSV is configured in two ways, first the non-adjustable SSV system and secondly, the SSV system with internal rebound adjustment. The internal rebound adjustment is accomplished by removing the top caps and inserting a hex key into the valve and either closing or opening for greater or lesser rebound damping. Catalog 2005 - 2005_Marzocchi_Catalog.pdf p.5

SSVF
SSVF
SSV with a floating valve for better small-bump response; external rebound knob.
SSVF is our "Speed Sensitive Valve Floating" with a specially designed Floating Valve that further enhances the SSV concept. The floating valve instantly lets oil start flowing through the first valve circuit with no resistance providing greater initial bump sensitivity. As oil flow becomes greater and faster the floating valve provides more oil flow resistance and hence more damping performance. The SSVF system uses an external knob to control the rebound speed. Both systems (SSV & SSVF) can be further fine-tuned by changes in the oil viscosity and valve porting. Catalog 2003 - 2003_Marzocchi_Catalog.pdf p.4
STA
Switch Travel Adjust: a quarter turn of the top cap lowers travel by 40 mm (55) or 30 mm (44).
Derived from the tried and tested AER concept, the revolutionary hydraulic travel adjust system Switch TA is available for the 55 series (40mm) and 44 series (30mm). Catalog 2013 - 2013_Marzocchi_Catalog.pdf p.11
In 2001 Marzocchi developed its first travel adjust system, called ECC (Extension Climb Control), and redesigned it in 2003 under the name ETA (Extension Travel Adjust). For the 2012 line Marzocchi launches its completely new travel adjust system, called STA (Switch Travel Adjust)! A quarter turn of the top cap shortens the travel by 40 mm (55 series) or 30 mm (44 series), which makes climbing easier for the rider. Derived from the hydraulic AER system, it is an air cartridge with a hydraulic travel change system. The fork returns to its original travel automatically when the top cap is turned back to its original position. Catalog 2012 - 2012_Marzocchi_Catalog.pdf p.5 (translated from Portuguese)
TAS
Travel Adjustment System: a switch lowers the travel by 20 mm, e.g. 120 to 100 mm.
Our all-new TAS Travel Adjustment System offers 20mm of overall travel adjustment, so a 120mm travel fork adjusts down to a 100mm travel fork with a fl ick of a switch. It operates separately to the ETA or ECC designs and our idea with TAS is to offer an initial travel set-up, fine-tuning the overall ride height or balancing out the rear suspension. The ETA or ECC is used for on the fl y extension control. Catalog 2005 - 2005_Marzocchi_Catalog.pdf p.6

TST Micro is the greatest evolution of TST closed cartridge hydraulic systems. The black knob in the lower part of the fork leg allows adjusting the rebound. The red-coloured top knob allows activating the Micro System to adjust the compression. The Micro adjustment (golden knob on the top of the fork leg) sets the operating threshold of compression by adapting the behaviour of the suspension system to the type of terrain. Lockout is activated by turning the golden knob completely in the closed position, then shifting the red lever. In some models, the TST system can be activated by means of the remote control in the handlebar. Catalog 2009 - 2009_Marzocchi_Catalog.pdf p.3
To ensure a fork's ideal performance, it is key to keep oil and air completely separate. We were the first to introduce a bladder system on a mountain bike cartridge; a design taken from motocross technology. The bladder can inflate to expand when the shaft goes inside without any air getting in. Slightly redesigned to reach perfection, the TST Micro is the latest step in a forward evolution of our closed cartridge hydraulic system. The red knob on the lower part of the fork leg adjusts rebound; the black top lever activates the Micro system controlling compression. The Micro adjustment located in the middle of the top left knob sets the threshold valve in order to offer maximum traction and control on any terrain and combining it with any riding style. Lockout is activated quick and easy to not hold you back from your uphill adventure. Catalog 2013 - 2013_Marzocchi_Catalog.pdf p.11

TST5
TST5
5-position compression dial: open for descents, 2–4 for trail riding, 5 locks the fork for climbing.
The Marzocchi TST5 (Terrain Selection Technology 5) is a classic 5-position damping system for Marzocchi suspension forks and shocks (fitted to models such as the Marathon, Corsa and All Mountain from the mid-2000s).
How it works & features
• 5-position dial: a dial with five positions sits on top of the right fork leg or on the shock.
• Position 1 (open): maximum sensitivity and use of the travel for rough descents (downhill).
• Positions 2–4 (medium): progressively firmer compression damping for trail riding, to reduce pedal bob when pedalling out of the saddle.
• Position 5 (lockout): the fork is almost completely locked for efficient climbing on tarmac or gravel.
• Bladder system: many TST5 cartridges work with an internal bladder and need a special fork oil (usually SAE 7.5w) and specific service tools when serviced.
VA
Volume Adjust: one knob sets spring preload (sag) and air/oil volume together.
The 888 RC2X and 888 RC2 models are the only forks on the market to offer Volume Adjust technology. VA simultaneously adjusts the preload of the fork springs to set the SAG while at the same time reducing or increasing the air/oil chamber. The VA adjustment is accomplished by a separator that moves up or down with the preload adjuster, this separator either increases or decreases the air/oil chamber. Simply put, it's like adding or decreasing the oil volume to control the bottom out resistance with a simple turn of a top mounted CNC knob. Now that's technology. Catalog 2007 - 2007_Marzocchi_Catalog_-_2007CAT-INTL.pdf p.4
Tuning the preload, rebound and compression is not always enough. Some riders want to control the compression curve from the beginning to the end of the stroke. What they need is our exclusive Volume Adjust; the easiest way to control the second half of the compression keeping maximum control in all riding conditions without sacrificing any of the legendary plushness. All it takes is theturn of a knob and without the need of changing the oil level. Catalog 2013 - 2013_Marzocchi_Catalog.pdf p.11
