Swap a tired bottom bracket for one built to be serviced, not thrown away. Hope's threaded BB for 30mm crank axles uses the same design as its proven 24mm version: machined aluminium cups holding stainless steel cartridge bearings in stainless races, with a free-running labyrinth seal to keep grime out without adding drag.

Highlights

  • For 30mm crank axles in BSA threaded frames
  • CNC-machined aluminium cups
  • Replaceable stainless steel cartridge bearings
  • Free-running labyrinth seal for low drag
  • Suits road, MTB, DH and fat bikes (shell width dependent)
  • Six anodised colours

Built to last

Stainless bearings give a much longer life than typical stock units, and when they do wear, the bearings are replaceable, so the cups keep going. Hope quotes 102g for the 30mm version.

Compatibility & fit

For BSA (threaded) frames and cranks with a 30mm axle. Check your shell width against Hope's BSA threaded BB compatibility chart before ordering. Fitting needs Hope's specific 30mm BB tool, sold separately. Some power-meter cranks do not clear the BB cup – check clearance first. Fitting is a separate Tune Cycles workshop service and is not included in the price – book a workshop appointment.

Covered by the manufacturer's warranty against defects in materials and workmanship. For warranty support, return the item to Tune Cycles with your proof of purchase and we'll manage the claim for you. This is in addition to your rights under the Australian Consumer Law.
