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 1.5 volume spacers on Fox 36 modelsCompatible with FOX 2018-2025 FOX 36 Factory, Performance Elite, Performance, and Rhythm models, including E-tuned versions.
