We spent two months and logged a total of 1,609km putting 15 bike tools through dozens of en route and at-home repairs, and found the Topeak Mini 9 to be the best multi-tool for casual cyclists. If you're willing to pay more for a lighter tool, check out the Specialised EMT Pro Road. If you're a mountain biker, the Crank Brothers m19 has the additional tools you need. And for you single-speed/fixed-gear folks, the Park Tool MT-30 has a wrench for removing bolted wheels.
