The BlackBearing Pressfit30 bottom bracket allows a 30 mm axle crankset to be fitted to a PF30 standard frame. Available in a ceramic version, this bearing type is lighter, offers greater rigidity, less friction, and a longer service life than steel bearings.
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 bearings’ lifespan, and making installation and removal easier.
