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 <a href="https://public-repository.org/marzocchi-fork-seal-chart/" target="_blank" rel="noopener noreferrer" style="color:var(--brand);font-weight:600;text-decoration:none;">Forks <-> Seals Chart ↗</a> — 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 <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?
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 7 28 / 30 / 32 / 35 / 38 and 40mm. For 30mm and 32mm there are2 seal kits available. The difference is the outer dust seal which come in 'classic' (flanged) or 'm-arch' style (non-flanged).
Yoou also can consult our public <a href="https://public-repository.org/marzocchi-fork-seal-chart/" target="_blank" rel="noopener noreferrer" style="color:var(--brand);font-weight:600;text-decoration:none;">Forks <-> Seals Chart ↗</a> — 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, <a href="/account/tickets/new" style="color:var(--brand);font-weight:600;text-decoration:none;">open a ticket</a> 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!
If you have done everything right, that's nearly impossible. Check you have the right side up for the oil seals. Make sure you 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. Also never 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.
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 <a href="https://public-repository.org/" target="_blank" rel="noopener noreferrer" style="color:var(--brand);font-weight:600;text-decoration:none;">public-repository.org ↗</a>.
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 on your way.
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.<br><br>Custom productions we don't take back as these have been arranged for you only. Sorry.<br><br>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.<br><br>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 https://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 UPD 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!🫵

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
