Our 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.
If using adapters, remove each adapter from bottom bracket bearings. Some adapters can be pulled out by hand. If needed, use a punch and tap on the adapter from the opposite side of the bottom bracket.
Use a large punch, or headset removal tool, and place end of punch so it is pressed up against the back side of the bearing seat (red area behind bearing as shown in photo).
Tap cup out using hammer. Force needed to remove will vary from frame to frame.
Repeat process for other cup.
Clean and inspect bottom bracket. Remove any grease/dirt and prep for installation.
