Vorsprung Suspension Lufkappe
The 2017 Vorsprung Suspension Luftkappe is an upgrade kit for RockShox forks. The replacement air piston reduces initial spring rate and required damping, increases sensitivity to the smaller disturbances, and keeps traction high. Performance is exceptionally smooth through the middle ranges. Kits are user-installable and rebuildable; parts are readily available from the company, which also offers installation and maintenance services.
A very good addition to RockShox Pike, Yari, and Lyrik forks.
