DT Swiss Service/Upgrade Kit 54T for Ratchet EXP Hubs Online

DT Swiss Service Kit/Upgrade Kit for renewal or replacement of sprockets.

In the DT Swiss Ratchet EXP System, each tooth engages with its front surface in a tooth of the opposite disc (engagement angle). Thus, lower point loads are generated than with the triangular ratchet system. This results in the legendary reliability of the Ratchet System hubs and the unmistakable sound when the pulleys are turned against each other. For cyclists, it is important that the power is immediately converted into propulsion when starting off. Therefore, DT Swiss pulleys are available with different numbers of teeth and correspondingly different engagement angles. The smaller the contact angle of the timing belt pulleys, the less empty travel is available when pedaling.
