Rotor BB4224 BB MTB Steel Black

ROTOR BB4224 BB MTB. Your brand loyalty is admirable; your acute knowledge of so-called standards gets tested every time you add a new bike to the stable. In a perfect world, you'd be able to easily swap out parts based on what kind of riding you feel like doing that day. But guess what? In a less-than-perfect world, for you ROTOR designed the BB 4224 for your BB30 shell to accommodate your cranks with a 24mm axle. The BB 4224 is the "yes" component to "Is this compatible with my BB30 bottom bracket for a 24mm axle?"
