DT Swiss RWS Thru Axle As one of the strongest wheel mounting systems on the market, the RWS (Ratchet Wheel-mounting System) Thru bolt is the perfect way to add some muscle and solidify the rear end of your rig. DT Swiss's RWS tightens skewers with turns rather than using a cam, providing up to 50% more clamping force than conventional quick releases. Additionally, a multi-position lever with a red alloy release button allows lever angle/ clocking after tightening.
