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. Overall size 7" x 3" x 0.125".
We took the guess work out of finding a bottom bracket. Get all your measurements with the Bottom Bracket Gauge and then visit our new online bottom bracket fit finder webpage to find a product that will work for you
