BSA30 ceramic bottom bracket converts English thread frames to fit 30mm spindle EVO386, Rotor 3D+, Rotor 3DF, THM and Zipp cranks. But BB30 standard cranksets won’t work with this system.
This is a very ideal conversion bottom bracket to run an EVO386 30mm cranks on an English thread (BSA) frame without spacers.
However, with the other cranks such as Rotor 3D+ there will be two spacers required but all come with the bottom bracket.
