For their 2017 lineup Fox will adopt a new cartridge for entry level performance and Rhythm forks. This is the FIT Grip cartridge, inspired by the hydraulics operating motorcycle forks and based on a FIT sealed cartridge system that’s already been adopted on top end forks for several years and now in its fourth version.
Unlike normal FIT cartridges from FOX, the FIT Grip has been simplified with the adoption of a spring to control the internal floating piston in the cartridge which handles compression damping.
Inspired by moto fork damping systems, FOX’s new GRIP damper uses our FIT sealed cartridge technology combined with a coil-sprung, internal floating piston. The system allows excess oil to purge through a specially designed port at the top of the damper to maintain consistent damping and increase durability.
FIT GRIP dampers are used in Performance and Rhythm Series forks, bringing a new level of ride quality and adjustment to those price points. Performance Series forks provide Open, Medium, and Firm modes with additional micro-adjust between settings, giving riders added control to fine-tune their damping needs. Rhythm Series forks offer 2-position sweep adjust, giving riders a wider range of damping adjustment and performance never seen before at this level.
Below it is an example of how the range is divided up : Performance and Rhythm that will adopt the new FIT Grip cartridges. Note that the Performance version is available in both Aftermarket and in OEM, while the Rhythm version is designated specifically for the OEM market.
