Back in 2000, Cannondale revolutionized bottom bracket technology by oversizing the bottom bracket shell and replacing the heavy, flexy steel BB spindle with a 30mm aluminum spindle with a unique, stress-reducing wave-taper crank interface. The result was BB30, a system that is not only significantly lighter, but also significantly stiffer than traditional designs. We released the design as a free industry standard and the rest, as they say, is history.
