DT Swiss Rear Hub 240s Boost DBIS 12x148mm 32 Hole 6Bolt XD

240 The number to count on – 240 with Ratchet EXP and Ratchet DEG. The 240 is designed for riders with the most extreme ambitions. You have the choice whether you want to count on the 240 with a weight advantage from the DT Swiss Ratchet EXP system or with the small engagement angle of the patent pending DT Swiss Ratchet DEG. The EXP system offers fewer parts and is available in 36 and 54 teeth. Ratchet DEG offers 90 teeth, but also ensures the well-known reliability thanks to its larger design.
