Show Description

Size matters. Too big or too small and you’ll be stripping threads, wobbling wheels, or grinding bearings. This precision stainless steel ruler takes the measure of most things you’d be putting on your bike.

Built-in gauges for:

  • Crank cotter sizes (8, 8.5, 9, and 9.5).
  • Spoke length (all sizes).
  • Ball bearing sizes (1/8, 5/32, 3/16, 7/32, and 1/4in.)
