MRP Noken High Volume Air Cap Preserves Small-Bump Compliance The MRP Noken is a spring upgrade that increases air-spring volume, reducing the compression ratio and creating a more linear spring curve that mimics the plush feel of a coil spring. This simple upgrade addresses a key challenge for many riders with long-travel forks: finding the right balance between a supple initial stroke, strong mid-stroke support, and fully utilizing all the fork's travel. With the Noken, you can optimize that perfect trifecta. Features Preserves small-bump compliance and mid-stroke support, while also regaining the travel that is typically lost due to the harsh, steep progression of some stock air springs Creates a more linear spring curve with a less dramatic spring rate change near bottom-out Installs with a 32mm six-sided socket Compatible with either Rock Shox Zeb (A1+) or Fox 38 Factory/Performance Elite/Performance models Increases the positive spring volume | Mrp | Noken High Volume Air Cap Rockshox Zeb
