The X-Fusion O2 Pro RLX is an air rear shock for cross-country, trail and all-mountain riding, with three-position compression adjustment and a handlebar-remote-compatible lockout. This trunnion-mount version is sized 185x55mm.

Highlights

  • Air spring with a larger-volume air canister for a smoother ramp-up
  • Three-position compression adjustment: open, pedal, lock
  • Rebound adjustment
  • Optional 7-piece mounting hardware for reduced drag and longer bushing life
  • Additional Volume (AV) air-sleeve option for a more linear spring curve

Damper and adjustment

RLX models get three-position compression adjustment (open, pedal, lock) alongside rebound adjustment, built around X-Fusion's updated air-canister design for a smoother, more linear spring feel.

Compatibility & fit

This 185x55mm trunnion shock is one of six trunnion sizes in the O2 Pro range (165/40, 165/45, 185/50, 185/55, 205/60, 205/65). Recommended air pressure runs between 60psi (4.14 bar) minimum and 300psi (20.68 bar) maximum. Our workshop can fit and set up the shock on a compatible frame.
