Crank Bros have opted for function as the number 1 priority with the M10 leading to a tool that you could easily use everyday for all manner of bicycle maintenance, not just occasional emergency use. Having to carry a separate chaintool is the only issue with the M10 so look at its big brother the M17 if that is an issue
All functions are of a practical length for easy use
Made of quality materials backed up with a lifetime guarantee
One of the heaviest multitools on test
Lacking a chaintool
The Crank Brothers M10 Special Edition multi-tool offers a lesson in functionality by including the 10 most commonly used tools to cover most eventualities out on the road. All of the tools are of a sufficient length to comfortably tackle the job of loosening or tightening stubborn bolts and are made of 6150 high-tensile steel.
The retaining body is made up of two slim yet comfortable knurled alloy rods. The M10 comes complete with 2-8mm Allen key sizes, including a 2.5mm, plus Phillips and flathead screwdrivers and a Torx T25 for disc rotors, all of which fitted well, while the slimmer size of the tool allowed good access in restricted areas.
The only issue with choosing the M10 as your only multi-tool is the lack of a chain tool; for this you will need to look at the M10’s bigger brother, the M17. This apart, the M10 is a great little tool to use at home or on the go.
