A rail that allows the basket or, for example, the pump to be moved 9 degrees to either side. In total, you get 18 degrees of yaw. Side deflection for right and left-handers. Especially suitable for frames with a massive frame tube or full suspension frames, where often poor handling of the perch due to collision with the shock absorber occurred. Material: 6061-T6 Weight: 24g includes screws Recommended tightening torque: 3-4 Nm Maximum load: 1700g per rail Made in USA
