Split second reactions to rapidly approaching terrain must be translated smoothly through the bike for the rider to have genuine control. The TRIAIR was designed to handle the abuse of long, challenging descents while maintaining consistent damping, holding a steady line. Supported by an air-backed IFP in the piggy chamber, riders can adjust this as well as easy volume spacer adjustment to dial in the desired spring curve. The 3CR damping allows for 3 position compression adjustment and 8-clicks of rebound range to create the proper balance between fork and shock. TRIAIR is QSP designed for reliability and serviceability, and is the perfect match for the Durolux, Auron, and Aion.

With the PCS as the foundation and completely new designed shim based high-speed compression and rebound circuits, our new R2C2 cartridge is progress in the right direction with our testing data providing proof. Simple, reliable, durable and easy service performance.
