BB30 - 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 designs. Along with a 30 mm spindle, it requires an oversized 68 mm or 73 mm bottom bracket shell and press fit bearings held in place by snap rings.

Details:

• Outer diameter: 42 mm
• Diameter spindle: 30 mm
• Shell width: 68 - 73 mm
• Weight approx.: 64 g

Please note: Picture 2 shows the mounted version. Shell is not included in the delivery.
