Hope's PF46 bottom bracket takes the guesswork out of 46mm press fit shells. The bearing cups are pressed in and held by a screw-in centre tube, preventing slipping and play for a quiet, secure fit.

Highlights

  • Cups held by a screw-in centre tube to prevent slipping and play
  • Replaceable stainless steel cartridge bearings
  • For 24mm or 30mm crank axles
  • Suits 68, 73 and 83mm PF46 shells
  • Short versions for cranks with shorter axles
  • Weight from 112g (Hope figure)

Choosing a version

Pick your frame's shell width, then your crank axle diameter. The 30mm "Short" 83mm version assembles to 83mm wide (versus 111mm for the standard 83mm/30mm unit) — Hope's compatibility chart shows which suits your crankset.

Fitting

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