The RWS Thru Axle from DT Swiss for the new 148 mm Boost Standard. This thru-axle has a flat contact surface on the lever side and is therefore only compatible with the E-Thru standard with a thread gauge of M12x1.5.
The patented RWS wheel mounting system from DT Swiss is stiff, safe and easy to use. After tightening the thru axle, the lever can simply be turned to the desired position. The direct transfer of leverage to the thread allows the RWS to achieve up to 50% more clamping force than conventional quick-releases.
