DT-Swiss RWS Thru Axles Doing the most in axle technology, the newpatented RWS wheel mounting system from DT Swiss is stiffer and safer than a conventional quick release. The ratcheting system tightens the Thru Axle by rotation, rather than using a cam. Once tightened, the lever can be rotated into the desired position, so it stays tucked out of the way. If you prefer a cleaner look or you are looking for added security, the Plug-In version allows you to remove the lever all together and stow it away in your pack, or perform double duty by using it as a 5mm mini hex tool. Rotating Lever: Lever handle can rotate after tightening, NOT removable from axle Plug-In Lever: (Pictured) Lever handle is removable, features mini 5mm hex key that inserts in axle Features User Friendly Ratcheting System Rotating lever rotates for ideal positioning after tightening Plug-In lever can be removed for a cleaner look Plug-In lever has a built in 5mm hex key Alloy axle and lever Front Options: 12x100mm E-Thru Road Rear Options: 12x142mm, E-Thru Road, E-Thru Mountain and Syntace X-12 | Dt Swiss | Rws Plug In Throughaxles | Black | 12X100 E-Thru, Road
