It allows you to brake powerfully and promptly even when the hands are gripping high up around the hoods

Better distribution of handlebar tightening: The clamp that replaces the traditional cover also has another very important advantage: the handlebar clamp is much more homogeneous and powerful than with a cover held in place by 4 screws that do not always have the same clamping depth (number of threads engaged) or the same torque

they use flexible beads (TS)
