Maintenance and set up for MTB

In general we should replace oil and seals after every 30-40 working hours or once per year.

By working the suspension with too used seals we could end up with irreparable damages on the rods, having a much higher cost than a regular maintenance.

The oil replacement is key in order to keep the performance of the forks like the first day. Oil suffers from oxidation and thermal-mechanical wear, reducing the damping properties of your suspension and increasing the wear on the parts in contact.

In PR Suspensions we offer you 2 different levels for the maintenance :

Basic Maintenance :

1. Checking the initial state of the damper in the dynamometer
2. Disassembly and inspection of all parts
3. Control of guides and rods
4. Ultrasonic bath cleaning of the valves
5. Replacement of seals and gaskets
6. Oil Change
7. Adjust Nitrogen preload when needed
8. Final check on dynamometer of the entire range of settings

PRO Maintenance :

1. Checking the initial state of the damper in the dynamometer
2. Disassembly and inspection of all parts
3. Control of guides and rods
4. Ultrasonic bath cleaning of the valves
5. Replacement of seals and gaskets
6. Adjustment/modification of the valves and oil viscosity related to the rider’s weight and bike use (cross-country, enduro, downhill).
7. Adjust Nitrogen preload when needed
8. Final check on dynamometer of the entire range of settings

Why do we use Nitrogen instead of air?

There are several advantages when we set the preload with Nitrogen:

– Nitrogen doesn’t expand like the air when affected to temperature changes. Your suspension system will not have different behavior depending on the fork temperature. On the long down hills the damping will stay constant from the beginning to the end.

– This is an inert gas. By removing the oxygen and humidity there is no corrosion within the internal components, extending the lifespan.

– Oxygen molecules contained in the air are 4 times smaller than the Nitrogen ones. By using Nitrogen there is less mass loss along the time which translates into keeping the initial preload settings much longer than with air.
