ABP is so effective because it utilizes a concentric placement of the rear suspension pivot around the rear axle connected to Trek’s Full Floater suspension system. The concentric pivot is located directly between the seatstay and chainstay, and consists of a bearing riding on a spindle that is fixed to the swing arm. This placement creates separation between the brake forces and suspension function, allowing both systems to do their job unencumbered. Often described as a “floating brake”, the disk brake assembly is attached by a separate brake arm allowing it to “float” independent of frame and suspension motion. As a result, the relative rotation between the brake rotor and caliper is reduced compared to many other designs. ABP is distinguished from other multiple-linkage rear suspension designs because it allows for design tweaks to one part of the system without affecting the others. ABP separates how Trek conceptualizes the performance of braking, suspension, and pedaling systems, and allows for precise tuning of each aspect that influences ride quality. Riders can expect the traction and suspension action that come with complex linkage systems, along with the acceleration, response, and durability that would typically be found only with a single-pivot system. The result of these design innovations? More active suspension, increased braking power, and a faster, more controlled ride.
