Noken High Volume Air Cap - Compatible with RockShox Zeb Suspension ForkThe 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.
