DT Swiss 240 DEG MTB Hub

The DT Swiss 240 DEG hub for use on MTBs with Boost 148 rear ends.

The DT Swiss 240 DEG hubs offer maximum durability and reliability. Thanks to the larger 90-tooth pulleys, the DEG hubs provide uncompromising propulsion. The Ratchet DEG system is based on a similar principle to the classic ratchet system – with the difference that all components have an optimised size thanks to the pawl expanded to 90 teeth.

DT Swiss 240 DEG hub:

The patent-pending Ratchet DEG system is based on a different approach to conventional freehub systems. It operates with a smaller engagement angle, thereby offering maximum reliability. The innovative design of the Ratchet DEG hub allows the bearing to be replaced without special tools. The threaded ring does not need to be removed. The steel DEG pawls are larger than on any previous DT Swiss models. They are designed to make it easier even for the strongest riders to transfer power over the long term and across a large contact area. The simultaneous engagement of the sprockets results in a larger contact area than with ratchet hubs – and thus a more even distribution of the load. The two enlarged sprockets have 90 teeth. With just 4, they therefore offer the smallest engagement angle of any hub in the DT Swiss range. On the trail, this leads to reduced backlash. The Ratchet DEG freehub body has a larger diameter at the ratchet interface. This means it fits perfectly with the size-optimised DEG ring. Furthermore, it is therefore only compatible with hubs equipped with the Ratchet DEG system. The seal is located on the freehub.

DT Swiss DEG bearing spacing:

The Ratchet DEG system has a larger bearing spacing than the classic Ratchet system. The drive-side bearing is at the same height as the threaded ring but, unlike the Ratchet EXP freehub system, is not integrated. The innovative design of the Ratchet DEG hub allows the bearing to be replaced without special tools. The threaded ring does not need to be removed here.

DT Swiss DEG freehub body:

The Ratchet DEG freehub body has a larger diameter at the ratchet interface. This means it fits perfectly with the size-optimised DEG ring. Furthermore, it is therefore only compatible with hubs equipped with the Ratchet DEG system. The support width is greater than on all other freehub body systems. The seal is located on the freehub.

DT Swiss DEG sprockets:

The Ratchet DEG system and the new freehub body now allow the installation of size-optimised 90-tooth rings. This enables a 4° engagement angle. DEG rings are only compatible with Ratchet DEG hubs.
