Genuine DT swiss RWS (ratchet wheel system) replacement axel. The RWS axles allow for up to 50% more torque than your standard Quick release axel. Once the skewer is tightened to the recommended 15N.m, the lever can be adjusted by pulling away from the frame and placing in the desired position. This system keeps your skewer tight whilst discreetly hiding the lever behind the frame for those photoshoots.
