Manitou suspension forks have earned a solid reputation among mountain bikers for their performance and reliability. Over time, however, even the best forks need maintenance or upgrades. Whether you are rebuilding a worn-out fork, fine-tuning its feel, or repairing damage, knowing which parts for Manitou suspension forks to order is crucial. This guide walks you through the most common replacement components, how to identify your fork model, and where to source genuine parts without guesswork.

Common Parts You Might Need
Manitou forks share a modular design, but specific parts vary by model and year. Here are the components riders most frequently replace.
Seals and Dust Wipers
Seals are the first line of defense against dirt and moisture. Worn seals cause oil leaks and reduced performance. Manitou offers two types: foam dust wipers that absorb oil for lubrication and standard rubber wipers. Replacing both the dust wiper and the main seal is recommended during a lower leg service.
Bushings (Sleeves)
The bushings in the lower legs guide the stanchions smoothly. As they wear, play develops, leading to friction and poor alignment. Manitou uses specific bushing sizes for each chassis (e.g., 32mm, 34mm, 36mm). When ordering parts for Manitou suspension forks, always check the stanchion diameter and the numeric code on the existing bushing.
Damper Cartridges and Internals
The damper controls compression and rebound. Manitou’s designs include the MC, MCR, MCS, and newer Tech cartridges. If your fork feels too soft, too harsh, or lacks adjustment range, the damper may need servicing. Rebuilding a damper with fresh oil and seals is common, but sometimes the entire cartridge must be replaced. For older forks, sourcing a complete cartridge upgrade (e.g., from MC to MCR) can dramatically improve performance.
Air Springs and Coil Springs
Manitou forks use air springs or coil springs depending on the model. Air spring assemblies include the piston, o-rings, and negative spring components. Leaks or inconsistent feel often trace back to a worn air spring seal. Coil spring models (mostly on older or budget forks) require a correct spring rate for your weight. Both types are available as replacement parts.
Air Shafts and Bottomless Tokens
For air forks, the air shaft is a common upgrade to adjust travel. Shorter or longer shafts let you change the fork's travel. Bottomless tokens (volume spacers) allow fine-tuning of the air spring progression. These small plastic rings fit inside the air chamber. Adding or removing tokens changes how the fork ramps up near bottom-out.
Shock Rebond Oil and Grease
While not a physical part, using the correct viscosity oil is essential. Manitou specifies different oils for different dampers (e.g., 5wt, 7.5wt, 10wt). Grease for the dust wipers and foam rings should be Manitou’s own or a similar low-friction grease. Neglecting oil quality can lead to premature wear of internal parts.
How to Identify Your Fork Model for Correct Parts
Ordering the wrong part is frustrating and costly. To get the right parts for Manitou suspension forks, you first need to know exactly which fork you have.
Find the Model and Serial Number
Look on the back of the right leg (non-drive side). There is usually a sticker or laser etching with the model name (e.g., Manitou M30, Mattoc, R7, Minute, Circus) and a serial number. Write this down. The serial number helps verify the year and specific version.
Measure Stanchion Diameter
Stanchion diameter is one of the most critical measurements. Common diameters: 28.6mm (some older cross-country forks), 30mm, 32mm, 34mm, 36mm. Use a caliper to measure from the unworn top section of the stanchion. This determines compatibility with bushings, seals, and crown parts.
Check Travel and Axle Standards
Manitou forks are built for different wheel sizes (26", 27.5", 29") and axle types (QR15, 15x100, 20x110). If you are replacing the entire lower leg or axle assembly, confirm your wheel size and axle standard. Also note the travel — for example, a 120mm Mattoc and a 150mm Mattoc share many parts, but the air shaft and spring may differ.
Consult the Parts Diagram
Manitou provides exploded view diagrams for each fork model on their website. These diagrams label every component with a part number. Cross-reference your fork’s model and year to find the exact diagram. This eliminates guesswork.
Where to Buy Genuine Manitou Parts
For reliable fit and performance, always use genuine Manitou parts. Aftermarket seals or bushings may be cheaper but often lead to poor fit, increased friction, or seal failure. Genuine parts are engineered to the same tolerances as the original fork.
Authorized Dealers and Service Centers
Manitou has a network of authorized dealers and service centers that stock parts and can perform rebuilds. Buying from them ensures you get correct, manufacturer-supported components. Many also offer online ordering with model-specific listings. If you are unsure, call them with your fork’s serial number — they can look up the correct parts.
Direct from Manitou (Hayes Bicycle Group)
Manitou is part of Hayes Bicycle Group. Their website has a “Parts” section where you can search by fork model. Inventory may be limited for older models, but new or recent forks usually have full part availability. Ordering directly avoids third-party markup.
Specialized MTB Shops
Local bike shops that focus on mountain biking often carry Manitou parts or can order them. Building a relationship with a good shop helps with future maintenance. They can also help with installation if you are not comfortable doing it yourself.
Maintenance Tips to Extend Part Life
Knowing which parts for Manitou suspension forks to replace is only half the battle. Proper care can double the lifespan of your seals, bushings, and damper.
Regular Lower Leg Service
Every 30–50 hours of riding, or at least twice a year, perform a lower leg service: remove the lowers, clean the internal components, replace the foam rings (or oil them), and apply fresh grease to the dust wipers. This prevents dirt from grinding down bushings and seals.
Damper Rebuilds
Damper cartridges should be rebuilt every 200 hours or once a year, whichever comes first. This involves draining old oil, replacing seals, and refilling with the correct viscosity oil. If you notice a sudden change in damping performance, do not delay — running a low-oil damper can damage the cartridge.
Inspect Air Spring Seals
If your fork loses air pressure overnight, the air spring seal is likely leaking. Replace the seal and o-rings as a set. Keep the air spring clean during reassembly — a single dirt speck can cause a slow leak.
Use Compatible Lubricants
Manitou recommends specific oils and greases. Avoid using automotive grease or heavy oils—they can swell seals or cause stiction. Stick to manufacturer-recommended products for best performance.
Practical Recommendations for Buying Parts
When you are ready to purchase parts for Manitou suspension forks, follow these steps for a smooth experience:
- Start with a thorough inspection. Write down the model, stanchion diameter, travel, and axle type. Look for any stamped numbers on the lower legs or crown.
- Check the parts diagram. Go to the Manitou website, find your fork, and download the diagram. It lists every component with its part number.
- Order only the parts you need. If seals are leaking, order a seal kit. If the fork feels sticky, bushings may be worn. Don’t replace everything unless you are doing a full overhaul.
- Buy from a trusted source. Use an authorized dealer or direct from Manitou. Avoid general marketplaces where counterfeit parts are common.
- Consider upgrades. If your fork is older, upgrading the damper cartridge or air spring can be a cost‑effective way to improve performance without buying a new fork.
Ultimately, keeping your Manitou fork in top shape comes down to using the right parts and performing maintenance on schedule. With the information in this guide, you can confidently identify, order, and install replacement components to keep your ride smooth and controlled for seasons to come.
