The thru bolt RWS optimizes the RWS system even more. 10 mm rear thru bolt is used. Together with a DT Swiss thru bolt hub it offers an even better connection to the frame and fork than even a standard RWS as well as any other quick release. The RWS thru bolt system combines the advantages of a fixed thru axle with the ease of use of a standard quick release. The RWS thru bolt system is 100 % compatible with any standard frame or fork that would normally use a quick release. 10 mm / 135 mm
