Product Description

Rapid Drive 54 tooth SL Ratchet System

Some time in 2013 Bontrager asked DT to design and manufacture a custom tooth count ratchet drive to be used in high end Bontrager wheels. The result was an ultra light, 54 tooth “Rapid Drive” . By adding 18 teeth to the design, DT was able to decrease the engagement angle from 10 degrees to just 6.67. Originally intended for use in Bontrager mountain wheels that utilize DT Swiss internals, the Rapid Drive ratchet system will work with any road or mountain DT Swiss hub the uses the Star ratchet system. The SL ratchet kit is also manufactured using less material saving an extra grams over the Stock ratchet system that ships with 240 and 350 hubs. All ratchet systems are made from the same high grade steel.

These kits include 2 Ratchet Rings with replacement springs and a small container (20 grams) of DT freehub grease.
