The Shimano Saint bottom bracket is purpose built for gravity and downhill riding (threaded 68/73mm or 83mm option available). This Shimano Saint Bottom Bracket uses the Hollowtech II spindle interface, making it compatible with other frames that use threaded bottom brackets shells that are intending to use Shimano cranksets. In fact, the only difference between the two versions is the length of the plastic inner sleeve between the two bottom bracket cups. The threads on the drive-side of both 68/73mm and 83mm options are a bit longer than your standard Hollowtech II bottom bracket to accommodate BB-mounted chainguide systems. Not only will this help for downhill and gravity bikes, but could also benefit cyclocross racers running a 1x drivetrain and chain guide system.
