Stainless Steel BB30 bottom bracket bearings.

The Blackbearing bottom bracket range has been specifically developed to withstand the most extreme conditions.

The BBlock technology (built in 2 threadable parts) allows a better alignment of the casing in its assembly offering several advantages:

- minimizes possible cracks
- greater protection to the bearing extending its useful life
- an easier replacement of the bearing.
