SD BB30 Spinning Bottom Bracket - 24mm

SD BB30 SPINNING BOTTOM BRAKCET - 24MM

This SD Spinning bottom bracket is CNC machined from aluminum. It allows the installation of a crankset with a 24mm spindle on a frame with an external width of 68mm and an internal diameter of 42mm.

This bottom bracket features bearings with a conical outer race. Therefore, the bearings can only be mounted in one direction within the cups. The cups are also marked with "OUT" to indicate the external side. This technology enables automatic coaxial alignment for improved power output. Its easy maintenance feature ensures smooth operation over extended periods, while angular contact further enhances its reliability and longevity.

For installation, the bottom bracket has a 20-spline internal fitting on each side to accommodate a square-taper bottom bracket tool. This locking mechanism allows for easy installation. Its threaded structure helps prevent the intrusion of foreign objects and increases the rigidity of the bottom bracket.
