All the multi-tools in the E-version range are made from predominantly Chrome Vanadium steel, with steel side plates and connecting bolts. Looking at this Mini Tool in more detail, the Allen (hex) keys are 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, and 8mm. The spoke keys are 3.2mm, 4.3mm, 4.4mm, and a Mavic-specific fitting. The Torx keys are T25 and T15.

This E-Version 15-function Mini Tool is also available with a flat-head screwdriver instead of the T15 Torx key. The former is called the 'Standard Edition', the latter is the 'T15 Edition'. Testing the mini tool on a selection of components on the bikes in the road.cc lab, the individual Allen keys, and Torx keys all swung out of the tool very smoothly. When the pressure was applied, there was little sign of flexing, even at the pivot point where the Allen key hinges out of the multi-tool; this is because the base of each Allen key is drilled and completely surrounds the connecting bolt.

The spoke keys are built into the twisting lever of the chain tool, which has to be completely unscrewed from the chain tool to adjust the spokes. Not the work of a moment, but then nor is re-truing a wheel at the side of the road.
