Using the knowledge gained from their ‘Corset’ air can Vorsprung have created the ‘Luftkappe’. This air piston upgrade increases the negative air volume in your fork providing greater small bump compliance, suppleness, and traction while maintaining (and even improving) the forks middle and end stroke support.

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 more information and a complete list of compatibility options please visit the 'Vorsprung Luftkappe' product page on the Vorsprung website and scroll down to the bottom of the article.

Note: If your MY2018 36 Evol tops out noticeably, you will need to replace your air shaft assembly before purchasing the Luftkappe. 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.
