Ohlins RXF38 M2 Air TTX18 29 Custom Tuning

Tuning your Ohlins fork allows us to optimize performance for low-speed damping and high-speed damping inputs.

For compression, these inputs can be considered to be your bodyweight affecting the damper (low-speed, LSC) and terrain inputs (high-speed, HSC).

These inputs are "damped" by the TTX twin-tube damper which features in both the TTX shocks and the RXF and Dh forks.

Your LSC and HSC adjuster on the top of your fork or on your TTX damper gives you 15 clicks of useable adjustment for low-speed compression and rebound and 3 clicks of high-speed compression with the 4th click engaging your pedal platform or "lockout".

With the Ohlins settings bank, we can customise the damping force that your fork exserts irrespective of your adjuster settings and we have a wide range of tunes available for all weight ranges and riding styles.

The shim arrangement on the main piston dictates how much fluid is displaced into the HSC and LSC valves. Once we select the correct shim arrangement for your weight this force can be fine-tuned on your adjusters to get the perfect ride without getting lost in too many clicks!
