DT Swiss 240 Classic Rear Hub - EXP 54 - 6-Bolt - 12x148mm - SRAM XD

The number you can rely on - 240!

The DT Swiss 240 is designed for riders with the most extreme goals. The latest version of the legendary hub is equipped with the Ratchet EXP system to further increase the reliability of the hub. The increased bearing spacing increases bearing life, the straight spring precision meshes the sprockets, reducing wear, and a reduced number of parts not only makes maintenance easier, but also reduces weight.

More details of the DT Swiss 240 rear hub

Easy maintenance

DT Swiss hubs are known for their no-tool concept. The concept allows tool-free conversion to all common axle and freewheel body standards. All DT Swiss Ratchet System hubs can be converted.

Less weight

With the original Ratchet System, two springs were required for correct function because the internal sprocket was not attached to the hub shell. Integrating the toothed disc and threaded ring in the Ratchet EXP hub not only increases durability, but also reduces the number of components by using a single spring. It also reduces the weight of the freewheel system.

Full engagement

The tight connection between the inner sprocket and the hub shell of the Ratchet EXP hub ensures that the inner sprocket is always aligned at the correct angle. The use of a single cylindrical spring allows for faster, complete engagement, providing greater reliability.

Superior Reliability

Ratchet System hubs are unique in that all the teeth of the two discs engage simultaneously every time. In the case of ratchet hubs, the meshing area is quite small. In the case of the Ratchet System, however, the entire face surfaces engage with each other, resulting in a much smaller point load. The result is the legendary reliability of Ratchet System hubs.

Longer life

Bearing spacing is limited by the length of the freewheel system. With the previous system, the drive side bearing had to be placed next to the threaded ring, so the spacing could not be increased. By integrating the drive side bearing into the threaded ring, the bearing spacing is increased, resulting in improved axle rigidity.
