The RockShox SIDLuxe Ultimate 3P Rear Shock is the cross-country end of the RockShox range — a 210 x 50 mm SoloAir unit whose three-position damper switches between Open, Pedal and Lock from a bar-mounted remote. This is the A2 generation in RockShox's factory Reb81 / Comp27 tune with Mid 8 pedal tune and Lockout Force 8, the configuration specified for the Canyon Lux TR from 2022 onward. Rear shocks are frame-specific: confirm eye-to-eye, stroke, mount type, mounting hardware and shock tune against your frame manufacturer's spec before ordering.
