The riders with the most extreme ambitions trust our products. Riders should be able to focus 100% on their goals and shouldn't have to worry about their material. It doesn't matter
whether their goal is to become world champion or simply to ride their bike every day regardless of the conditions, they can always count on DT Swiss.
For these riders we have further developed the 240 hubs and equipped them with the latest Ratchet EXP system to maximize reliability.
Increased Bearing Lifetime
The integration of the bearing into the threaded ring allows the bearing distance to be maximized. The increased distance further supports the axis, which results in less deflection of the axle and thus protects the bearings and increases their lifetime.
Faster Full Engagement and less wear
The previous system required two conical springs to ensure proper alignment of the two ratchets. The fixed connection of the inner ratchet of the RATCHET EXP with the hub shell allows to use only one cylindrical spring, to ensure proper alignment of the moving ratchet. This results in faster full engagement and eventually reduces wear
Featuring an incorporated notch, the newly developed shape of the endcaps simplifies disassembly significantly and therefore makes the maintenance even easier.
The full engagement of the ratchets creates a large contact surface and therefore low surface pressure that leads to superior reliability.
Not only the reliability improved. The fusion of ratchet and threaded ring reduces the number of single parts of the system what offers an important advantage.
