THE DEFINITIVE SUSPENSION SYSTEM

Award Winning Quad Link Suspension Continues to Set the Benchmark

The award winning Marin Quad Link 2.0 system provides riders with an efficient pedaling platform while managing terrain by modifying the axle path of the wheel and leverage ratio of the shock to simultaneously react to pedal and bump forces.

QUAD-LINK 2.0 : KEY SUSPENSION SYSTEM COMPONENTS

Design:
While the concept of the Quad Link 2.0 system is the same as the original design, the new version provides a slightly more linear action for suspension movement. Like the first gen Quad Link, the rear wheel's axle path and leverage ratio on the shock changes as the wheel moves through its travel to provide optimized control and energy transfer. This is accomplished by having the swingarm rotate off of the two Quick Links that connect the swingarm to the mainframe. Movement: Because the swingarm is mounted to two links, it does not rotate from a single point, or pivot. Instead, the swingarm "floats" or rotates from a constantly moving pivot point in space. This pivot point is called the Instantaneous Pivot Center(IPC). Because of this changing pivot location, the shock's leverage ratio and the axle path of the rear wheel change to allow the suspension to react differently to pedal or bump induced forces. The initial pivot point begins above and forward of the BB to provide a higher leverage ratio on the shock. When the suspension is first compressed the rear axle travels in a rearward and up direction, increasing the effective chainstay length and providing a greater leverage ratio on the rear shock.

Results:
These features add up to better square-bump compliance and reduce the tendency of having the bike stall when encountering an impact (especially important to maintain speed while coasting through a corner or when trying to clean that technical climb). The lengthening of the effective chainstay also creates chaingrowth during the first 1/3 of travel, which promotes the rear wheel to dig into the ground and maintain traction under pedaling force. Midway through the travel the axle path changes to an arc around the BB, yielding zero chainstay growth to allow the wheel to freely move without any pedal induced interference while the leverage on the shock gradually decreases to slow compression and resist bottoming on hard landings. The result is a constantly adjusting suspension system that allows the suspension to easily react to small bumps to maintain traction and reduce rider fatigue while providing greater control under hard impacts or landings. A lifetime warranty on all bearings ensures that the suspension will operate smoothly for the duration of ownership.

Benefits:
- Progressive shock leverage ratio resists blowing through travel and bottoming out on large impacts

- Short links equal quick change in leverage ratio to quickly adapt to trail conditions

- Intelligent Wheel Path moves rear wheel backwards and over the small hits

- Superior tire and mud clearance not characteristic of other 4 bar systems

- Chaingrowth early in the travel resists bob and improves traction

- Zero chaingrowth later in the travel virtually eliminates bob and pedal-induced lockout

- Lifetime warranty on bearings

- Patented 4 bar 4 bolt system exclusive to Marin minimizes wear and tear on pivot points while reducing weight
