Rotor BB30-24 Reducer Road BB Steel Blk
Rotor BB30-24 Reducer Road BB Steel Blk
  • Ceramic bearings
  • Non-contact labyrinth seals
  • Fits BB30 frames
  • Compatible with cranksets that use 24mm spindles

Rotor made the BB30-24 Converter Mountain Bike Ceramic Bottom Bracket for people who want to run the crankset they like, regardless of spindle diameter. The BB30-24 makes installing a conventional 24mm spindle diameter in a BB30 frame possible.

Buttery-smooth ceramic bearings keep you rolling faster and longer inside of their aluminum cups. To add unrivaled protection against dust, water, and mud, ROTOR used new, non-contact labyrinth seals.

The plastic caps that snap into the bearings now provide some compressive relief in the slip-fit between the spindle and the inside diameter of the bearings thanks to an updated design by Rotor.
