SD BOTTOM BRACKET BB386 - 24MM

This SD bottom bracket is CNC machined from Aluminium. It allows you to install a crankset with a 24mm axle on a frame with an external width of 86mm and an internal diameter of 46mm.

This bottom bracket has the unique feature of working with bearings that have a conical outer shell. The bearings can only be installed in one direction in the cups. The cups also have an OUT designation to indicate the outer side. This technology allows for automatic coaxial alignment, improving power output. Its easy maintenance functionality ensures it can operate smoothly for long periods, while the angular contact further enhances its reliability and longevity.

For installation, the bottom bracket has a 20-tooth internal profile on each side to insert a square axle type tool. This locking mechanism allows for easy installation. Its threaded structure helps limit the intrusion of foreign bodies and increases the rigidity of the bracket.
