Three primary features that made Quad-Link successful continue forward to Quad-Link 3 :

• Instantaneous Pivot Center (IPC) Technology

  The heart of Quad-Link, the moving pivot center reacts to both pedal input and bump force to allow seamless wheel movement over terrain while efficiently transferring rider effort to the rear wheel.

• Intelligent Axle Path

  Because of the Quad-Link's design of attaching the swingarm to the main frame via the two Quick Links, engineers can alter the arc of the rear wheel as it moves through its travel. A unique feature with Marin's Quad-Link design is the rearward wheel path during the initial movement of the suspension. This allows superior square bump performance by allowing the wheel to roll up and over obstacles- essential for maintaining contact over braking bumps while descending and maintaining momentum and traction while climbing up and over obstacles. During the latter part of the wheel travel the axle path follows an arc around the bottom bracket, allowing the suspension to freely absorb impacts without pedal-induced lockout or bobbing.

• Varying Shock Leverage Ratio

  The second benefit of the Quad-Link's attachment of swing arm and mainframe is the ability to alter the leverage ratio between the shock and the rear wheel as it moves through its travel. While still a rising rate suspension design, the Quad 3.0's system has been revised to offer a more linear suspension rate. Essentially, as the wheel moves further into the travel more force is needed to compress the suspension. The benefit is a suspension system that is very active in its initial travel to increase traction when climbing and sprinting while resisting bottoming out on hard impacts and landings. Because these features are a part of the suspension system itself, and not the shock, riders are given the freedom to choose shocks from their favorite manufacturers and not have to worry about being stuck with proprietary parts.
