If you own a 27.5 or 29" SID, REBA or Bluto fork (32mm chassis), you can update your fork with the new updated Charger2 Damper™. The Charger2™ is RockShox’s most refined damper, and its sealed construction with an expandable rubber bladder ensures damping consistency, and reduces vibration. Adjustment is easy and intuitive, with a single compression adjuster, low-speed compression adjuster and a beginning stroke rebound adjuster with a factory set Rapid Recovery™ tune. The internal shim stacks can be re-tuned for light or firm compression and rebound settings.
