The easiest way to tune the geometry of your full suspension bike. Installing eccentric shock reducers allow to modify the geometry of the frame by shortening the eye-to-eye length of the shock.  This result in a slacker head tube angle and a lower BB. Our eccentric reducers are designed to shorten the length of the shock of 3mm. Depending on the suspension design BB can be lowered from 5 to 10mm and the head angle from -0,5º to -1º.
