DT Swiss 240 EXP Rear Hub
Developed for riders with the most extreme ambitions, the DT Swiss 240 rear hub is equipped with the Ratchet EXP system to maximize reliability and reduce weight.
- 240 Hub is lighter, stiffer, more precise and easier to maintain than previous versions
- Ratchet EXP is the lightest freehub system from DT Swiss
- Increased bearing distance increases bearing lifetime
- Straight spring provides more direct engagement, which reduces wear
- Fusion of the ratchet and threaded ring reduces the number of single parts in the system, further reducing the weight
- 36 points of engagement offer a great balance of performance and weight savings
- Full engagement of the ratchets creates a large contact surface and therefore low surface pressure that leads to excellent reliability
- Featuring an incorporated notch, the newly developed shape of the end caps simplifies disassembly for maintenance
- Rear hubs featuring the SRAM XD freehub standard are compatible with both 11- and 12-speed cassettes
