Wheels Manufacturing PressFit 30 Bottom Bracket – N/A
The original PF30 bottom bracket is a significant upgrade to any OEM PF30 bottom bracket. Two machined aluminum cups with replaceable bearings offer increased durability and bearing life, while keeping a simple press together method for installation and maintenance. This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement. Specifically designed for installing 30mm spindle diameter cranks in PF30 (46mm ID BB shell) frames without the need for any adapters.
