RockShox SID Select 3P D1 Suspension Fork Built with a stiff, lightweight 35mm chassis and the Charger RL damper 3P damper with three compression positions (Open, Pedal and Lock) to choose from for the most efficient ride. DebonAir+ provides more small-bump sensitivity and mid-stroke support. Updated Bushing Package maximizes the fork’s bushing overlap, reducing friction and creates the smoothest ride possible. Bolt-in torque cap adapters included for use with standard hub end caps.
