Bottom Bracket: PF30 68 to 86mm

Our PF30-68-86 Bottom Bracket is machined from alloy instead of some flimsy plastic. It is more durable and less prone to deforming during installation and use. It is compatible with BB shells from 68 mm to 73 mm for BB30 cranks or can be extended to 86mm for BB386 cranksets. Even extended it remains fully sealed and aligned for proper bearing alignment, reducing drag and extending bearing life.

It has multiple O-ring seals to help prevent the contamination of your bearings by water, grit, or grime.

It comes with spacers and wavy washers to be used as needed
