Lighter, stiffer, more precise and easier to maintain - The DT Swiss 240 hub.
Swiss precision, from high-precision machining to perfect assembly, combined with intelligent detail solutions have made the 240 hubs what they are today - A legend! The strengths of the 240 hub, have been further developed with the RATCHET technology. The super reliable freewheel system ensures a direct power transmission without losses. Exactly what athletes need - perfect transmission of their power and absolute reliability, so that you can concentrate exclusively on cycling.
The DT Swiss 240 is the top hub for extremely lightweight wheels. The aluminium hubs are assembled by hand at DT Swiss, so they are 100% Swiss Made. The advantages of the 240 are its low weight, the sealing system against water and dirt, as well as the stainless ball bearings with a special coating for silky smooth running and minimum resistance.
DT Swiss believes in engineering and strives for perfection when developing new products. The guiding principle here is to keep pushing the technological boundaries.
Ratchet System hubs are unique in that all the teeth of the two discs mesh simultaneously every time. In the case of ratchet hubs, the meshing area is quite small. In the case of the Ratchet System, however, the entire face surfaces engage with each other, resulting in a much smaller point load. The result is the legendary reliability of Ratchet System hubs.
Bearing spacing is limited by the length of the freewheel system. With the previous system, the drive side bearing had to be placed next to the threaded ring, so the spacing could not be increased. By integrating the drive side bearing into the threaded ring, the bearing spacing is increased, resulting in improved axle rigidity.
