The patent pending Ratchet DEG® system was designed by taking a different angle than the common high engagement freehub systems, to deliver a smaller engagement angle and maximized reliability.

The innovative construction of the Ratchet DEG hub allows bearing replacement without special tools, as the threaded ring does not have to be removed.

Made of steel, the DEG ratchets are bigger than all the previous DT Swiss ratchets and aim to transmit the power of even the strongest riders for a long time and across a large contact surface.

Two enlarged ratchets with 90 teeth offer the smallest engagement angle ever made in the DT Swiss portfolio: 4º. On the trail, this transmits into a different angle in the backlash.

The Ratchet DEG freehub bodies have a bigger diameter at their ratchet interface to suit the size optimized DEG ratchets and are therefore compatible only with Ratchet DEG equipped hubs. The seal is located on the freehub.
