This SD Components bottom bracket is specially designed for BMX Race. It allows you to install a crankset with a 24mm axle on a frame with an external width of 68mm and an internal diameter of 42mm. I
t's referred to as "BB30 to 24mm" because it features resized bearings tailored specifically for 24mm axles. The internal diameter of these bearings is 24mm.
The SD bracket offers both rigidity and practicality. Thanks to its threaded installation system, it can be mounted without the need for a press; simply tighten the two bearings together using a Shimano-type specific wrench.
Fast, efficient, and stiff—these are the terms that perfectly describe this SD Components bottom bracket.
