What to Compare Before Buying
- Shell fit: Check the bicycle’s actual bottom bracket shell measurement and the cup fit specification. A frame-style label alone cannot confirm fit.
- Crank and threading: Confirm the bicycle uses a one-piece crank and check the stated 15/16 inch x 24 thread against its requirements.
- Bearing specification and contents: Compare the stated 5/16 x 9 caged bearings with the required specification. Check the selected set’s contents if you need to know which components make up the 9 pieces.
Compatibility, Size and Fit
Beach cruiser, lowrider and chopper frames are named as possible applications, but those styles do not establish exact compatibility. Verify the shell fit, thread and crank configuration for the specific bicycle before choosing the set.
Before You Decide
Confirm the bottom bracket shell fit and thread, check that the bicycle has a one-piece crank, and verify the set contents if the exact component count matters. Follow the bicycle and component manufacturers’ instructions for installation.
