Hope's answer to the press fit minefield: bearing cups that thread into a centre tube, so the whole assembly is locked together in a threadless PF46 shell rather than relying on the press fit alone.

Highlights

  • Cups thread into a centre tube to stop slipping and play
  • Ceramic cartridge bearings
  • Designed for threadless press fit shells
  • Replaceable bearings and parts
  • Truvativ GXP conversion available separately

Secure and serviceable

Holding the cups together with a screw-in centre tube keeps them aligned and tight in the frame. When the bearings wear, they can be replaced rather than binning the whole unit.

Fitting

A specific Hope fitting tool is required (sold separately). Installation is a separate Tune Cycles workshop service — book a workshop service.

Built to be rebuilt

Like the rest of Hope's range, these bottom brackets are made to be serviced: parts are replaceable, so a worn unit can be refreshed in the frame's next service.

Compatibility & fit

Check your frame's shell standard and width, and your crank axle diameter, before ordering — we're happy to confirm fit.
