Description
No longer let your frame limit your crank choice thanks to the Rotor Italian Bottom Bracket to BB30 Steel.
They are so hardwearing that they have applications for road and mountain bike use. This is thanks to incredibly durable steel bearings.
This bottom bracket is used to convert Italian threaded systems to accept 30 mm axle systems. Fortunately, this means you can use all Rotor 30 mm axle cranks, the Rotor 3D+ crankset or most other 30 mm axle cranksets.
Rotor have also redesigned their contact labyrinth seals to maintain the silky smooth rotations by protecting the internals from mud, water and dust.
