The Bottom Bracket Gauge Tool was designed to provide all the necessary measurements to identify the proper bottom bracket for a specific bike configuration. The gauge can measure:
- bottom bracket width
- bottom bracket shell inner diameter
- crank spindle length
- crank spindle diameter
- bearing inner diameter
A metric scale runs along the long edges for measuring bottom bracket shell width and crank spindle lengths. Durable red anodized aluminum with laser etching.
