SBC-1 Spoke, Bearing, Cotter Gauge

To use, just hang the head of the spoke in the oblong hole and read its length on the scale. For crank cotters and ball bearings it works just like a gauge for drill bits. Since the markings are embossed, you will be able to read them time after time whether you use metric or fractions.

• Ideal for sizing spokes, ball bearings and crank cotters
• Has both metric and fractional spoke length markings
• Anodized aluminum with embossed markings to allow easy reading and long life
