The DT Swiss 54-tooth Star Ratchet Service Kit is a drop-in upgrade for riders looking to reduce engagement delay on DT Swiss hubs. By increasing engagement points from 18 to 54, the kit cuts the rotation needed to engage the drivetrain from 20 degrees down to 6.67 degrees — a meaningful improvement for technical terrain or stop-and-go riding where precise power transfer matters.
Installation is straightforward: remove the freehub body, swap in the new ratchets and springs, apply the included Molykote grease, and reassemble. The kit is compatible with DT Swiss 180, 240S, 350, 370 LN, and 540 hubs, making it a practical service option for a wide range of DT-built wheels already in the field.
