Compatibility: RockShox Pike B1+ (2018+), Rockshox Revelation A1+ (2018+) Includes: 1 airspring Activity: mountain biking Manufacturer Warranty: 2 years Saving money never felt so good with the RockShox Pike C1 DebonAir Air Spring Upgrade kit. This kit is a great way to get our dated suspension into the 2020's and on par with some of the best squish in the game. The kit easily replaces the factory air spring and brings our 35mm stanchioned forks into a new realm of squish performance.
