DT Swiss 240 Straightpull hub MTB CL

The new 240 hub with Ratchet EXP: lighter, stiffer, more precise, and easier to maintain. Swiss precision, from high-precision machining to perfect assembly, combined with intelligent detail solutions, has made the 240 hubs what they are today: a legend. The strengths of the new 240 hub have been further developed with the new Ratchet EXP technology. The super reliable freewheel system ensures direct power transfer without losses. Exactly what athletes need: perfect transmission of their power and absolute reliability, allowing them to focus solely on cycling.

Ratchet System Technology: The patented freewheel system with high-precision ratchet discs guarantees maximum load capacity and reliability. Thanks to the no-tool concept, the system is very easy and quick to maintain.

Engagement Angle Technology: The engagement angle refers to the degree of rotation a hub freewheel turns in neutral before it can convert the crank's rotational movement into forward motion. The smaller the angle, the faster the leg power reaches the ground. However, it is important to know that there are limits to the minimum possible angle, as the reliability of the freewheel system also partially depends on the angle. What makes Ratchet System hubs truly unique is the fact that all teeth of the two discs engage simultaneously every time. In contrast, with pawl hubs, only some pawls engage at the same time. Additionally, the contact surface of pawl hubs is quite small, while in the Ratchet System, the entire end faces engage, resulting in much lower point loading. This leads to the legendary reliability of Ratchet System hubs and the distinctive sound produced when the ratchet discs rotate against each other!.
