Overview
ABP is short for Active Braking Pivot.
Trek's ABP Linkage:
This design is essentially a linkage-driven single pivot, except that Trek uses a concentric dropout pivot at the rear axle. This allows them to mount the brake caliper to the seatstay rather than the chainstay.
Because the seatstays rotate less around the disc rotor than the chainstays as the suspension cycles, the effect of braking forces on the suspension (known as anti-rise) is significantly reduced.
In other words, Trek’s design works like a linkage-driven single pivot in terms of pedalling forces, but like a Horst-link in terms of braking forces. It’s kind of a hybrid.[1]
