Notre avis
David G.
Former professional team mechanic
The BlackBearing BB30 bottom bracket allows a 30 mm axle crankset to be fitted to a BB30 standard frame. Available in the B5 version, this grade of steel bearing delivers high performance and excellent durability.
This bottom bracket is designed with two machined aluminium cups that screw into one another for better alignment, reducing creaking, optimising smoothness and efficiency, extending the life of the bearings, and making installation and removal easier.
