FOX Air Shaft, for forks 36 Rhythm (2019-2023), travel 140 mm
The FOX Air Shaft 36 Rhythm is an original air piston for FOX 36 Rhythm forks, which determines the overall travel and thus the geometry of your bike. It allows you to restore the function of a worn air spring or change the travel to 140 mm without needing to buy a new fork, while maintaining full compatibility and reliability with the Float EVOL system.
The assembly includes a precision-machined piston rod made of high-strength aluminum alloy, a complete air piston made of durable polymer, and the necessary seals. High-quality workmanship reduces internal friction and ensures smooth suspension operation even under demanding use. During installation, it is recommended to perform a complete service of the fork's lower legs and use original FOX 20wt. Gold or 4wt oil, while the piston seals should be lightly greased with special lubricant for air chambers.
