Compatibility, Size and Fit
This bottom bracket is relevant where the bicycle frame and crank axle need to match the stated standards. The key fit checks are the frame standard and axle diameter, because both affect whether the part can be used with your drivetrain setup.
If your frame or crank uses a different standard, a different bottom bracket version will be needed.
Before You Decide
Confirm the frame standard and crank axle size before choosing an offer. Check that you need a press-fit bottom bracket, and make sure the 24 mm, 29 mm or 30 mm axle support matches your bike setup.
If your bicycle uses a different standard, choose a different version rather than forcing the fit.
