Keep a compatible three-pawl DT Swiss hub and change the way it engages. This Ratchet LN kit replaces the pawl mechanism with a pair of face ratchets, bringing DT Swiss's broad engagement surface and serviceable construction to the existing wheel.
This road kit has a Shimano 11-speed road freehub and 18-tooth ratchets.
For supported DT Swiss 370 three-pawl hubs only. Ratchet LN has its seal on the freehub body, so a regular Ratchet or Ratchet EXP freehub is not a substitute. Confirm the exact hub and kit part number in DT Swiss Product Support.
Initial conversion requires the appropriate pawl and ratchet ring-nut tools. DT recommends a qualified mechanic for the installation. The complete kit stays together as supplied.
The two ratchet faces engage together, spreading drive load across their teeth. That is the central change from the small contact areas of the original pawl mechanism, rather than simply fitting a different cassette body.
A serviceable system
Once converted, the Ratchet LN design gives access to the freehub and ratchets for routine servicing. Compatible ratchets can also change engagement response. Keep the correct LN body and seal arrangement when choosing replacement parts.
