Wrench

There are now several cycling multi-tools that sit inside the bike's steerer tube. The Granite Stash RT Ratchet Tool Kit offers a little something extra, however, since as its name implies, it includes a ratcheting socket wrench and nine bits.

Scientists have created a nanoscale wrench that has an opening of about 1.7 nanometers, roughly a hundred-thousand-times smaller than the width of human hair.

The Mill-Grip adjustable spanner provides a very viable alternative to the old fashioned shifting spanner, featuring non slip grip, left or right hand use and precise fit adjustment with one hand.
