Unior Spoke Ruler

Unior's handy Spoke Ruler is designed for measuring spokes, ball bearings and crank cotter pins, in addition to just being a good work shop ruler. 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.

Cut from stainless steel with etched markings that have been filled with black paint for easy reading.
