When installing the Ezy or Ezy Superior adapters on your bicycle you need a thin wrench to properly tighten the axle to the crank arm. Failing to properly tighten the axle to the crank arm may result in stripped threads, or an injury. This 15mm box wrench is 3.2mm thick and 165mm long , allowing the maximum grip given the tight clearance.
You can make someone very happy by purchasing this tool so you don't have to resort to using a cone wrench!
