Rotor knows that committing to one bottom bracket system is potentially limiting, which is why it created the new BB30-24 Converter Mountain Bike Bottom Bracket. With this forward-thinking design, you're now able to run the crankset of your choosing, regardless of its spindle diameter.

With the new BB30-24 converter, Rotor makes it possible to install a conventional 24mm spindle diameter in BB30 frames. It relies on silky-smooth steel bearings for both their buttery feel and durability. Rotor's new, non-contact labyrinth seals were also added, providing both a smooth feel and unparalleled protection against dust, water, and mud.

Rotor also thought to improve the plastic caps that snap into the bearings. We often call them dust caps, but they have a structural place in the bottom bracket system, providing a bit of compressive relief in the slip-fit between the spindle and the inside diameter of the bearings.

The Rotor BB30-24 Converter Mountain Bike Bottom Bracket - Ceramic is available in the color Black. It will fit all BB30 frames and is compatible with cranksets using 24mm spindles.
