The precision-made saddle clamp clamps the seatpost in the frame as well as it looks. The designed clamping system aligns the screw thread and prevents it from bending. As a result, the distribution of clamping force is precise and less tightening torque is required to achieve a tight connection. Available in six diameters and several beautiful colours.
