FAQ
1. What is BB30 PF30?
Ans: BB30 and PF30 are both types of bottom bracket systems that utilize sealed bearings.
The BB30 system involves pressing the sealed bearing directly into the bottom bracket shell, while the PF30 system uses cups that are pressed into the shell, with the bearings pre-installed inside them. The main distinction lies in the size of the bottom bracket shell.
2. What is the difference between PF30a and PF30?
Ans: The PF30a is an adaptation of the PF30 standard, with the key difference being a 5mm wider BB shell on the non-drive side.
To accommodate this difference, thin spacers and/or a wave washer are used between the bearings and crank arms. These components help eliminate any slack and allow for micro-adjustments to the crank’s chain line.
3. What is the frame width of a PF30?
Ans: The frame width of a PF30 bottom bracket is 68mm for road bikes and 73mm for mountain bikes.
