Aerozine BB30 Kit Design for Road Racing & MTB Ceramic Bearings

Aerozine BB30 Ceramic Bearing Kit designed for Road, XC and All Mountain. BB30 is named for its required spindle size - cuts weight by up to 100 grams, narrows Q-factor, increases ankle clearance, and ups bearing durability. It's a fairly new standard involving different frame requirements and crank design. Along with a 30mm spindle, it requires an oversized 68mm or 73mm bottom bracket shell and press fit bearings held in place by snap rings.
