Do you ship worldwide?
Tracking is included on all orders. See our <a href="/shipping" style="color:var(--brand);font-weight:600;text-decoration:none;">Shipping & Delivery page</a> for rates and details.
Where can I find/buy Marzocchi forks?
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?
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?

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?
Can I order by phone or email?
How do I know my stanchion diameter?
I installed a new seal kit but the fork is still leaking!
As a Buyer : What can I do to make sure my sending arrives?
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?
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.
Do seal kits include dust wipers?
Where can I find Marzocchi documentation?
What's the best way to take care of my fork?
Regulary check air pressure and oil leve!
What happens to customers being rude, trying to sell me bullshit or trying trick me?
What Seal Kit Sizes are available for older Marzocchi Forks?
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?
Why are your prices so high?
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?
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 https://dhl.de, it is all about shipping product 2kg 'Paket'.
Why are you doing all this things about Marzocchi?
If you have a nice idea : Just do it.
What Marzocchi fork are you riding?
My daily Verlicchi Sintesi Bromont still has the Z1 BAM 130 mounted.
Why some of your seals are now gray instead of 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?
I have a cool retro/vintage bike project and need some support. I like to discuss with other Marzocchi lovers.
I'm a huge Marzocchi MONSTER 40mm fork fan. Where can I found spare parts, other Marzocchi fan's and lovers?
And there are more Marzocchi groups.
I'm a huge Marzocchi SHIVER DC UPD 35mm fork fan! Where can I found spare parts, Marzocchi fan's and lovers?
Why did you choose this website schema layout with the black header and the orange coloured styles?
This orange Bomber Z1 is still one of my favourites and one of my most supported Marzocchi forks!🫵

Troubleshooting
Typical Fork Problems
Common symptoms, likely causes and how to fix them.
| Problem | Diagnosis | Solution |
|---|---|---|
| Fork has too much sag | Spring rate too soft, spring rate too low (wrong spring for your weight) | Add spring preload · Change to stiffer spring rate · get a correct spring |
| Fork bottoms too easily · needs more than max preload to reach sag | Spring rate too soft · fork oil too low | Check oil height · Get stiffer springs · Increase air pressure |
| Fork bottoms too easily, but has recommended sag | Not enough compression damping | Increase compression damping by changing oil level |
| Fork does not get full travel | Spring rate too stiff · fork oil too high · spacers inserted | Check oil height · Get softer spring · Decrease air pressure · take spacers out |
| Fork extends too quickly · harsh top-out after impacts | Not enough rebound damping · oil level low | Increase rebound damping · Replace oil (SAE 7.5) with higher viscosity · fill correct oil level |
| Front wheel wants to tuck under while cornering | Too much rebound · dampingspring rate too soft | Decrease rebound damping · Increase spring rate |
| Fork "packs up" or stays down during multiple impacts | Too much rebound damping · bushings/stanchions friction | Decrease rebound damping · calibrate bushings |
| Knocking sound during rebound, but no harsh top-out | Too much rebound damping · oil level wrong | Decrease rebound damping · check oil level |
| Oil "ring" on stanchions | Oil seals are contaminated | ⚠ A small oil film is o.k and usefull, if it is more replace all seals, check fork inner details — repair the fork before riding again |
| Heavy oil on stanchions · oil dripping down legs | Seals damaged · stanchions may also be damaged | ⚠ Replace all seals + have stanchions inspected before riding again · stop riding : You are polluting the environment!! |
| Fork is sticky · does not perform as new | Oil seals contaminated · fork needs servicing | ⚠ Replace all seals — repair the fork before riding again · check bushings/stanchion friction -> you may need callibration |
| Oil leakage from the bottom | Loose bottom nut or bottom nut O-ring damaged | Tighten bottom nut · Replace bottom nut O-ring |
| Loss of sensitivity | Worn sliding bushings or old oil | ⚠ Replace sliding bushings · Change oil |
