Fox steps on the gas with cheaper forks
In 2015, Fox brought the damping technology up to date and introduced the FIT4 cartridge. This cartridge is found in the top models, and now the Californian suspension specialist is delivering an upgrade for the forks from the Performance and Rhythm lines. The new cartridge technology is called GRIP.
The GRIP damping is inspired by motorized off-road sports and consists of a sealed damping cartridge combined with an independent float piston with air spring. This design is intended to allow excess damping oil to escape during the suspension process through outlet openings - the so-called purge port - on the upper side of the damping. Fox promises more even damping behavior and better durability as a result.
The compression damping has also been upgraded: the Rhythm series has two modes to choose from, while the Performance forks have an even finer adjustment range, with the open, medium and firm positions offering three levels of compression speed.Further content on this article
