Shaft Assemblies can be used to increase or reduce the forks travel for both 27.5" and 29" wheel models. *Also suitable for Fox 36 Speed-Ped-Elec forks
When adjusting your forks travel you are also adjusting the ratio between;
Air Chamber Volume:Wheel Travel
For example, if you reduce your wheel travel travel you need to increase the number of Volume spacers to maintain the same level of progression.

Lower Leg Service
To fit the air shaft the lowers will need removing, why not carry out a lower leg service? Lower leg service kits HERE
