Description
BB30 is a standard that requires a 30 mm spindle, reducing weight by up to 100 grams. It narrows the Q-factor, enhances ankle clearance, and improves bearing durability. This standard involves specific frame requirements and crank design, including an oversized 68 mm or 73 mm bottom bracket shell and press-fit bearings secured by snap rings.
