The Diamond Ratchet is the drive engagement at the heart of every Scope rear hub. Replace a worn ratchet with the genuine part, or pick the 48T version for Race Series hubs.

Highlights

  • Genuine Scope Diamond Ratchet
  • 36T and 48T versions for Race Series rear hubs
  • 36T kit includes the flat spring
  • 36T ratchet is also used in Scope's Artech rear hubs

How it works

Scope's rear hubs use two face-toothed ratchets, one in the hub shell and one on the freehub body. The freewheel sound comes from the two ratchets turning over each other. Scope's manual asks for engagement grease on both ratchets when the hub is serviced.

Scope part numbers

Per Scope's exploded views, the 36T ratchet kit SC2021261 contains the Diamond ratchet 36T and flat spring SC2024223. It appears on MY21 and MY25 Race Series rear hubs and on Artech rear hubs.

Fitting is available as a separate Tune Cycles workshop service; it is not included with the part.

Scope's warranty covers manufacturing and material defects but lists pawls, springs and freehub parts as wear-and-tear items, so normal wear is not covered. For warranty support, return the product to Tune Cycles and we'll manage the claim with the brand's Australian distributor.
