DT Swiss 240 Classic Road Center Lock Disc Rear Hub

DT Swiss 240 Classic Road Centre Lock Disc rear hub - a modernised classic for road bikes

In the disc brake version, the 240 Classic Road rear hub from DT Swiss is the state of the art for modern road bikes. This is also due to the new freehub technology from DT Swiss. The Ratchet EXP freehub uses the advantages of a ratchet with 36 teeth. These offer optimum power transmission and prevent undesired idling. Bearings integrated into the threaded rings increase the distance between the bearings. As a result, the axis moves less, which leads to a lower load on the bearings. For this reason the hub is also stiffer. Due to the no-tool concept, you can service the 240 Classic without tools and change the freehub body.

Technology:

Ratchet EXP:
A ratchet and a threaded ring are integrated into the hub. This reduces the number of components required, resulting in less wear and tear and a lower weight. In addition, the heavy-duty and reliable ratchet system can be easily and quickly maintained. The no-tool concept plays a decisive role, as it allows the freehub to be replaced without any tools. The freehub has two ratchets which engage simultaneously. This means that the contact surface is large and the point load is kept small, which relieves the material and allows the freehub to work particularly reliably and precisely.
