If you own a Pike B1+ or Revelation from 2018 onwards, you can update your fork with the Charger 2.1 RC2 Damper™ Upgrade kit.

Features
Extruded bladder design is insanely durable, resists damping change during extended downhills and has virtually zero pressure offset for small bump sensitivity.
Ex factory, the damper unit is already filled with 3 WT oil and bleed.
