Abstract
A damper for a bicycle having a primary unit and a remote unit that, in some arrangements, is substantially entirely outside of the primary unit. The remote unit comprises a remote fluid chamber and, in some arrangements, an inertia valve within the remote unit. The inertia valve is preferably responsive to terrain-induced forces and preferably not responsive to rider-induced forces when the shock absorber is assembled to the bicycle. The inertia valve, which is configured to slidably move within the remote reservoir unit relative to a reservoir shaft, comprises a main portion and at least one protective coating or layer configured to contact the reservoir shaft. The protective coating or layer helps shield said main portion from contact with reservoir shaft, advantageously providing wear resistance, anti-friction properties, durability and other benefits to the damping system.
