Hubs

The number to count on—240 with Ratchet EXP. The new 240 is developed for riders with the most extreme ambitions. The latest version of the hub is equipped with the Ratchet EXP system to maximize reliability. The increased bearing distance increases bearing lifetime, the straight spring provides more direct engagement (which reduces wear), and a smaller number of parts not only makes maintenance easier, but also reduces weight.

The pinnacle among the hubs–Ratchet EXP united with SINC ceramic bearings. The premium 180 hub convinces with its sophisticated Ratchet EXP technology, giving the hub extra lightness, stiffness, and precision along with easy, no-tool maintenance. Furthermore, assembled with the low-friction SINC ceramic bearings, the hub performs efficiently and brings your power directly to the road. The hub is available for straight pull spokes only.

Direct power transmission in every riding situation—240 with Ratchet EXP. With the latest generation of the 240 hubs, the strengths have been further enhanced.
