Hope's threaded bottom brackets are renowned for their durability, and this is the everyday workhorse of the range. Machined aluminium cups hold stainless steel cartridge bearings in stainless races, sealed by a free-running labyrinth seal that keeps dirt out without adding drag.

Highlights

  • CNC-machined aluminium cups
  • Stainless steel cartridge bearings in stainless races
  • Replaceable bearings
  • Free-running labyrinth seal for low drag
  • 68-73mm and 83mm shell versions
  • Six anodised colours

Built to last

Stainless bearings give a much longer life than stock units, and they are replaceable, so the cups carry on. It is a simple way to add a flash of colour that matches Hope hubs, headsets and brakes.

Compatibility & fit

For threaded (BSA) frames: 68-73mm for standard shells, 83mm for downhill shells. Check your crank's axle size and Hope's BSA threaded BB compatibility chart before ordering. 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.
