BB30-24 Converter Bottom Bracket

The Rotor BB30-24 Converter bottom bracket makes it possible to install standard 24mm bottom bracket spindles into BB30-specific frames. The Converter uses the same ceramic hybrid cartridge bearings as a BB30 or PressFit 30 system. Rotor also added its new non-contact labyrinth seals for a silky-smooth feel and unparalleled protection against dust, water, and mud.

Superb Product

Familiarity:
I've put it through the wringer

Like so many others, I have experienced the BB30 blues: a squeaky, creaky, snap-crackle-pop bottom bracket, so poorly designed that it must be cleaned and re-lubed every 300 miles of use. Rotor's converter solves the problem. The only criticisms I have of it are that there is a slight weight penalty compared to the original BB30 and the pretty anodized surface mars easily upon first installation and removal. Using an aluminum removal tool (e.g. the one made by Chris King) helps minimize the marring. Otherwise, a great product. One correction to the above description: the bearing are 6905s, not 6906s.

Will this work w/ BB30a?

Do the ceramic bearings have a grade 3 or a grade 5 rating? Thanks.

Can I use this BB with a Dura-Ace FC 9000 crankset?

Yes, this will work
