Make your air fork feel like a coil.

Type:

Description

Taking everything we learned with the Corset air sleeves, the Luftkappe is a new air piston assembly that enlarges the negative air chamber to reduce the initial spring rate, allowing for a higher air pressure for more support in the middle and end of the stroke with improved sensitivity in the start of the stroke.

Features:

Coil-like feel without the harsh bottoming of a completely linear spring
Larger negative air chamber
Lower initial spring rate
Increased sensitivity
Improved mid stroke support & control
Superior bump compliance and traction
Reduced hand fatigue
Reduces required compression damping
Retains Bottomless Token compatibility
Optional 10mm shaft clamps available for self-install

For 2019 onwards, Fox have updated this part due to the topout issues that many of the 2018 36 Evol forks had. 34 forks do not have this issue. Relevant Fox part numbers for the new air shaft assemblies, by travel: 180mm: 820-02-534-KIT 170mm: 820-02-535-KIT 160mm: 820-02-536-KIT 150mm: 820-02-537-KIT 140mm: 820-02-538-KIT 100mm (36 831): 820-02-539-KIT If your fork does not have noticeable top-out issues, you don't need to replace the shaft before installing the Luftkappe.
Fox 36 (Float NA2 Evol) E-bike Specific [SPD-PED-ELEC]	Note that this fork usually requires the 34 Float NA2 Evol Luftkappe due to its thicker stanchions having a smaller ID. Exceptions exist - eg Giant e-bikes, which still use the 36 Float NA2 Evol Luftkappe as they are standard 36s despite the e-bike stickers on the fork.
