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. bbfinder
