 This system enables finer tuning of suspension kinematics, as the shock angle relative to the linkages during the travel changes in a more linear fashion.Trek also combines "Full Floater" with its "ABP" rear axle, where the rear suspension pivot is the rear axle, which reduces pedal feedback and prevents the braking forces on the wheel from altering the suspension movement.It also provides better traction and control through braking over rough terrain.
