With the MRP Control Cartridge, the progression of the air spring can be adjusted without tools. Similar to the tokens now commonly used by Rock Shox, the cartridge can be used to adjust the air chamber volume. In contrast to the tokens, the initial spring travel and middle spring travel remain largely unaffected, according to MRP. The cartridge is speed-dependent, which means that the sensitivity at the beginning of the spring travel is practically unaffected. Incidentally, a higher progression basically achieves the following: the fork provides more resistance at the end of the suspension travel and effectively prevents the dreaded bottoming out or bottoming out in the event of heavy impacts or compressions.

Which forks does the cartridge fit on?

The Ramp Control takes on the task of one to five tokens and, with two different threads for different forks, is suitable for Rock Shox Pike, Lyrik, Yari and Boxxer World Cup forks (only for Solo Air models).
