THIS GUIDE REFERS TO A H_RaTCHET DBL FREEHUB BODY SWAP ON OUR 42 LIMITLESS GRAVEL ADVENTURE WHEELSET.


  1. Remove the wheel from the bike and remove cassette if fitted.
  2. Pull the drive side end cap from the axle – no tools are required.
  3. With the freehub body, this simply slides off the axle. The H_Ratchet DBL is likely to stay in place within the hub body. Should it come out, please note the orientation in preparation for re-installing.
  4. To service the freehub mechanism, clean the H_Ratchet DBL and ratchet rings of the freehub body with a dry microfibre cloth and lubricate with a thin layer of lightweight grease on each surface.
  5. Fit the H_Ratchet DBL onto the drive side of the axle, with the sprung side facing outwards. Then slide the freehub of your choice on. You may have to turn the H_Ratchet DBL a little to slide into the ratchet ring teeth.
  6. Push the adaptor/end cap back on to the drive side of the axle. Please Note: if swapping from SRAM XD or SHIMANO HG to SHIMANO Microspline  or vice versa the drive side end cap is specific to the freehub body.
  7. Ensure that the adaptors are fully pressed home to ensure proper fit and prevent any lateral play.
