Complete Air Spring Cartridge Assembly - 170mm, For RXF38 m.2 Fork

Ohlins Complete Air Spring Cartridge Assembly for the RXF38 m.2 Fork delivers the precision and tunability Ohlins suspension is known for. Designed for riders who demand total control over their fork’s feel and performance, this complete 170mm air spring assembly offers a straightforward upgrade or replacement that brings factory-level performance back to the trail.

At the heart of this cartridge is Ohlins’ advanced three-chamber air spring system. Riders can fine-tune the main spring pressure through the top valve for overall support and responsiveness, while the ramp-up chamber at the bottom of the fork allows external adjustment of end-stroke progressivity—ideal for dialing in bottom-out resistance on aggressive descents. The third, self-balancing negative spring ensures initial sensitivity and small-bump compliance, and can be further refined by adding or removing up to two volume spacers to suit rider weight and terrain preferences.
