If you've been fortunate enough to be riding the OPEN O-1.0, then you've probably realized that your crankset options have been, well, limited. And while the included Rotor crankset is stellar, we're all guilty of our biases, and just as importantly, our preferences. That's why Rotor has created the Hollowtech 2 Bottom Bracket for the OPEN O-1.0. With it you're able to run your favorite Shimano Hollowtech 2 crankset with the OPEN's BB Right platform. So, you gain the smooth operation of Rotor's bottom bracket technology, the overwhelming rigidity of the BB Right platform, while gaining a much deserved touch versatility in your crank options.

The Rotor Hollowtech 2 Bottom Bracket for the OPEN O-1.0 is available in one color and one size.

Here's what others have to say...

is this for MTB or Road? I have a BbRighr...

is this for MTB or Road? I have a BbRighr Cervelo S5 and need to put a Ultegra 6800 (Hollowtech II) crankset on it. I think this'll do the trick. Am i right?

This Bottom Bracket is specifically for the Open Mountain bike frame. To the best of my knowledge, Open is the only mountain bike brand to use a BBRight system, and this BB was designed in conjunction with rotor for that particular application.
