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.Increases the positive spring volume by 1.1 Bottomless Tokens on RockShox Zeb (A1+) modelsCompatible with all generations of RockShox Zeb (A1+)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 springsCreates a more linear spring curve with a less dramatic spring rate change near bottom-outThe Noken is 10-13mm taller than standard damper control knobs, so it s important to confirm downtube clearance before installationInstalls with a 32mm six-sided socket MRP Noken High Volume Air Cap Air Springs & Parts UPC: 702430223607
