The Dt Swiss Ratchet DEG 90T DF 0/10/20 W Tool Service Kit featured here at Escapa is designed to eliminate unwanted pedal kickback on suspension MTBs. This system allows the hub to have a controlled range of rotation (0°, 10°, or 20°) before engaging, reducing the tension generated by the chain when the suspension compresses and improving the bike’s performance on technical descents. It is a direct upgrade for any Dt Swiss hub with a 90- or 72-tooth Ratchet DEG system, being lighter than other external solutions and fully adjustable without tools.
Direct power transmission offers clear advantages, especially in tough races or on technically challenging terrain. Thanks to a hollow milling of the toothed washers, the weight can be reduced by 10 grams per pair compared to standard toothed washers.
With 54 teeth, a pressure angle of approx. 6.7° is achieved to ensure very fast response under all conditions.
NOTE: Toothed lock washers and springs must always be replaced at the same time!
We recommend using special Dt Swiss grease to lubricate the toothed lockrings.
