This is SD Race Components' BB30 bottom bracket kit for frames with a 42mm bottom bracket shell, including 2018 and later Meybo frames and other brands running BB30. The bearing de sign is BMX specific, and the bearings are held in forged, CNC machined aluminium cups that ride on the outside of the shell for more durability.Two versions are available. The 24mm version suits SD Expert Lite, Pro and Pro Hollow cranks as well as Shimano, Rhythm, Bombshell and other cranks using a 24mm spindle. The 30mm through type suits cranks with a 30mm axle, but it does not work with Box Two M30 cranksets. Either version weighs 128g. Show more
