SD BOTTOM BRACKET BB386 SPINNING - 24MM

This SD Spinning bottom bracket is CNC machined from aluminium. It allows for the installation of a crankset with a 24mm axle on a frame with an external width of 86mm and an internal diameter of 46mm.

This bottom bracket features bearings with a conical outer ring. The installation of the bearings in the cups can only be done in one direction. The cups also have an "OUT" marking to indicate the outer side. This technology allows for automatic coaxial alignment to improve 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 the installation of the bottom bracket, it has a 20 internal spline on each side to insert a tool for “square axle” type bottom brackets. This locking mechanism allows for easy fitting. Its threaded structure helps to limit the intrusion of foreign bodies and increases the stiffness of the bracket.
