Excellent 44mm BSA bottom bracket bearing

- Peter, 31 August, 2020

I have been looking for a long time for a solution for a 44 mm BSA bottom bracket. The Tiagra bottom bracket that came standard on my bike wore out too quickly. Other Shimano solutions did not fit well. This is the solution for my bike.

Pros & Cons

Black
Good bearings
Good fit
No grip on threads as with Shimano
