Know before you buy
This unit is designed for frames with a 42mm BB30 shell and is compatible with both 68mm and 73mm shell widths. It specifically allows you to install a Shimano Hollowtech II crankset into that frame.
Unlike standard press-fit bearings that can shift slightly under load, the threaded aluminum shell locks the two sides together. This creates a more stable, rigid interface that prevents the movement typically responsible for bottom bracket noise.
Yes, this bottom bracket uses high-quality Enduro bearings that are fully replaceable. This means you can swap out the bearings when they eventually wear out rather than replacing the entire bottom bracket assembly.
Yes, you will need a bottom bracket wrench compatible with standard external bearing cups to tighten the threaded shell. We recommend using a high-quality grease on the threads during installation to ensure a smooth fit and prevent future seizing.
It weighs 127 grams. While it is slightly heavier than a basic press-fit setup, the trade-off is significantly improved bearing alignment and a reduction in maintenance issues.
