Wheels Manufacturing BB30 to Shimano Bottom Bracket

This bottom bracket is designed for frames with a 42mm shell diameter and a width between 68mm and 73mm, including standard BB30 and Specialized Alloy OSBB frames. It is specifically engineered to convert these frames to accept 24mm spindle cranks.

This unit is compatible with 24mm spindle cranks, including Shimano Hollowtech II, FSA MegaExo, and RaceFace EXI systems. It allows you to run these cranks on a BB30 frame without needing separate adapters.

Angular contact bearings are designed to handle both radial and axial loads simultaneously, which is ideal for the side-to-side forces generated while pedaling. This typically results in smoother performance and increased durability compared to standard radial bearings.

Yes. By using a two-piece threaded design that locks the cups together, this bottom bracket eliminates the movement often found in standard press-fit systems. This secure interface is the most effective way to prevent the creaking noises common in BB30 setups.

The Enduro bearings are replaceable. This makes the bottom bracket a long-term investment, as you can service or swap out the bearings when they eventually wear out rather than replacing the entire assembly.

Yes, you will need a bottom bracket wrench compatible with the specific cup design to thread the two halves together. Because it is a threaded system, it is generally easier to install and remove than traditional press-fit bearings, but it does require the proper tool to ensure it is tightened to the correct specification.
