Mountain biking brings with it many inherent risks and it’s not uncommon to have a mechanical or to need to make minors adjustments on the trail. It’s always a good idea to carry a multi-tool so you can straighten handlebars, adjust rubbing brake calipers, tighten loose water bottle bolts, and splice broken chains back together. Even if you don’t know how to make all these adjustments yourself, you should still carry a multi-tool so that a more mechanically-inclined rider can assist you if the need should arise. That’s why we’ve compiled this list of the best multi-tools for mountain bikers.
What to look for in a multi-tool for mountain biking
The best multi-tool for you will depend on your individual needs. Multi-tools run the gamut from stripped-down, lightweight tools that are great for weight-conscious riders and cross-country racers, to heavy-duty tools with features that make them useful beyond the bike, and everything in between.
At a bare minimum, your multi-tool needs to have the Allen and Torx bits required to tighten and loosen the critical fasteners on your stem, seatpost, brakes, shifters and make adjustments to limit screws on your derailleur. Generally speaking, this means your tool should have 3, 4, 5 and 6mm Allen keys, a T25 Torx, as well as Philips and flathead screwdrivers.
If you’re not worried about counting each and every gram, we suggest sticking with a multi-tool that also has a chain breaker, so you can repair damaged chains.
The best multi-tools for mountain biking
There are a lot of quality multi-tools on the market, but these are the best multi-tools we’ve tested and would recommend to fellow riders. With all multi-tools, there’s a trade-off that must be made in terms of how many functions they have in order to remain light and reasonably compact. We’ve broken them down by the number of tools starting with small and light and going up in functionality.
