Bottom Brackets

A bottom bracket is an important part in the drivetrain off your bicycle. It connects the crankset to the frame and transfers the power produced by the rider. To reduce friction, CEMA places SRC ceramic or full Stainless Steel bearings in CNC machined cups. Less resistance to ride faster!

Interlock

To increase the rigidity of a pressfit bottom bracket, CEMA pressfit bottom brackets are designed with an Interlock system. Both sides of the pressfit bracket are threaded together inside the frame. This will optimise power transfer and avoid noise issues and cracking!
