Wheels Manufacturing BB30A Bottom Bracket

This specific model is designed exclusively for the Cannondale BB30A standard, which features a 73mm shell width and 42mm shell diameter. Please verify your frame's specific bottom bracket shell standard before purchasing, as it is not compatible with standard BB30 or other press-fit systems.

This unit is compatible with 22/24mm spindle cranksets, commonly found on SRAM GXP systems. It will not work with 30mm spindle cranks or Shimano Hollowtech II cranks.

The primary advantage is the threaded design, which locks the two cups together securely within the frame. This eliminates the movement often associated with press-fit systems, which is the most common cause of persistent creaking and clicking noises.

Yes, you will need a bottom bracket tool with a 44mm, 16-notch interface to install the cups. This is a standard size used by many external bottom bracket tools, so you may already have one in your workshop.

Yes, one of the main benefits of this outboard design is that the bearings are serviceable. When the time comes, you can replace the Enduro angular contact bearings without needing to replace the entire cup assembly.

Angular contact bearings are designed to handle both radial and axial loads simultaneously, which is ideal for the forces applied during pedaling. This results in a smoother rotation and increased durability compared to standard radial bearings.
