4mm & 5mm allen head bolts are the most common sizes on a bike, so Runwell has crafted a perfect little tool that can make quick work of loosening and tightening without flipping through a bunch of little keys or carrying a multi tool.

A total length of only 70mm makes it very portable, and the paracord wrap is a nice touch for adding comfort to the handle and easily hooking the tool onto your keys or bag.
