Repairing a Bike on Side of Road

There are about a million bike multi tools to choose from, and it can be tough to figure out what you need. Rest easy—we’ve got you covered with our picks for the best bike tools of the year. Mechanical problems happen on the trail. Carrying the right bike tool can mean the difference between getting back on your bike and walking back to the trailhead.

Here’s our picks for the best bike tools to carry:

Best Bike Tools

crankbrothers f15 multitool



Crankbrothers F15

There aren’t many multitools that are this useful and this small. Here’s what this one packs:

  • 2, 2.5, 3, 4, 5, 6, 8mm hex wrenches
  • Phillips #2, flat #1 screwdrivers
  • 0, 1, 2, 3 spoke wrenches
  • Torx T25
  • Chain tool

The magnetic case, which serves as part of the chain tool, also includes a bottle opener. The only drawback of the tool’s small size is the chain tool. It’s tiny and not the easiest to use. If you plan on doing some chain repairs, you may want to go with something a bit larger.

If you want to fit a lot of tools in a small space, the Crankbrothers F15 a great choice. Just know that you can go too small.

crankbrothers m19 multitool

Crankbrothers M19

Need a few more tools than the F15 has? The M19 may be the answer. Here’s what it packs:

  • 2, 2.5, 3, 4, 5, 6, 8mm hex wrenches
  • Phillips #1 and #2, flat #2 screwdrivers
  • 0, 1, 2, 3 spoke wrenches
  • Torx T10, T25
  • 8, 10mm open wrenches
  • Chain tool

The chain tool on the M19 is a bit easier to use than the one on the F15. And because you have an extra Torx size, another screwdriver, and a couple open wrenches, you should be able to solve just about any problem you come across on the trail.

The M19 is slightly larger than the F15, but the difference is minimal. You don’t get a cool case with a bottle opener, though, so you’ll have to learn to use your other tools for a post-ride brew! A great bike tool set rolled into one.

topeak mini 20 multitool

Topeak Mini 20 Pro Tool

We’ve done 15 tools, we’ve done 19 tools, and Topeak is here to step it up one more notch. A full 20:

  • L-shaped 2, straight 2.5, 3, 3, 4, 5, 6, 8, 10mm hex wrenches (no, that’s not an error; there are two 3mm wrenches)
  • #2 Phillips, flat screwdrivers
  • 3 spoke wrenches
  • Torx T10, T25
  • Chain tool
  • Tire lever

And, just to top things off, a bottle opener. Having a tire lever is nice, but it’ll be a pain to use. You’re probably better off carrying a Quik Stik or a Crankbrothers Speedier. If you’re going for the lightest possible setup, though, it’s nice to have one on your multitool.

Topeak manages to pack all of these tools into a very small, very light making it one of the best portable bike tools on this list. So you’re getting a lot but not paying for it in weight. Be aware of that if you have big hands.

Price: $39.99

lezyne sv 11 multitool

Lezyne Sv 11

Bells and whistles? Lezyne is happy to oblige. This is one of the lightest multitools of the bunch, and packs 11 different options:

  • 2, 2.5, 3, 4, 5, 6, 8mm hex wrenches
  • Flat screwdriver
  • Torx T25, T30
  • Chain tool

That’s it. But what more do you really need? You probably already have a tire lever that you like. You don’t need a bottle opener. You don’t often need spoke wrenches on the trail.

The one thing to note about this tool is that it includes a T30 instead of a T10. If your bike uses T30 bolts, this is a no-brainer.

Price: $47.00

park tool ib-3 multitool

Park Tool IB-3

A high-quality tool with everything you need at a price that won’t break the bank. It’s a winner all around, an essential bike tool to carry. The Park IB-3 is the perfect combination. Here’s what you get with this signature blue tool:

  • 1.5, 2, 2.5, 3, 4, 5, 6, 8mm hex wrenches
  • Flat screwdriver
  • 0, 2 spoke wrenches
  • Torx T25
  • Chain tool
  • 8mm open wrench
  • Tire lever

One thing to note is that this is one of the very few multitools that includes a 1.5mm hex wrench. I’m not sure what you’d use that for, but if you need one, this is a great tool for you.

The IB-3 is heavier than many more versatile multitools. But the detachable tire lever, along with Park Tool’s sterling reputation, might make it worth it. It’s still really light. These guys are known for making some of the best professional bike tools on the market.

Price: $27.00

oneup edc multitool

OneUp EDC Pump

Let’s take a look at something really different. OneUp’s everyday carry (EDC) system takes your tools out of your backpack and puts them on your bike. Let’s take a look at the tools and then talk about how you carry them:

  • 2, 2.5, 3, 4, 5, 6, 8mm hex wrenches
  • 0, 1, 2, 3 spoke wrenches
  • Flat screwdriver
  • 0, 1, 2, 3 spoke wrenches
  • Torx T25
  • Chain tool
  • Tire lever
  • Top cap tool (for use with EDC top cap)
  • Presta valve core tool
  • Spare chainring bolt
  • Quick link storage
  • Sealed storage capsule or CO2 cartridge

You get a few extras with the EDC that are great for modern mountain bikes; the valve core tool is nice for tubeless tires, a spare chainring bolt never hurts, and a place to keep your extra quick link is really convenient.

But where the EDC shines is storage. You have two options: inside the steerer tube of your fork and inside a frame-mounted hand pump.

Here’s what it looks like stored inside the pump, which has an integrated CO2 inflator head:

oneup edc pump

If you want to get the tool set into your steerer tube, you’ll need the EDC tap kit and top cap. If you want to keep it in a pump, you have two options: the 100cc hand pump and a 70cc variant.

There’s a plug and plier kit, too, for plugging tubeless tires and getting quick links out of chains. And there’s more. You can get absolutely everything in the EDC system.

Price: $59.00

industry matchstix multitool

Industry Nine Matchstix

If you thought keeping tools in your steerer tube was cool, wait ’til you see this. Industry Nine built a multitool into a front axle. It doesn’t pack as many tools as some other options, but it has the essentials:

  • 2, 2.5, 4, 5, 6mm hex bits
  • Torx T25
  • Chain tool
  • Quick link storage
  • Valve core remover

Strangely, only four of the six bits fit into the axle. So you can only bring the ones you’re most likely to need (or throw the others in your pocket). This is all about convenient storage, not bringing every damn tool you can think of.

I9 makes this thru-axle available for a wide variety of forks and sizes:

Price: $145.00

spurcycle multitool

Spurcycle Tool

If you want light, you want titanium. And Spurcycle is here to give it to you. The mini bike tool, kit creatively called “Tool,” is a titanium driver with steel bits. Here’s what it includes:

  • 2, 2.5, 3, 4, 5, 6, 8mm hex wrenches
  • Phillips #2 screwdriver
  • Torx T10, T25

That’s it. Just the stuff you need. All rolled up in a pouch that’s made in the USA. Plus it only weighs a scant 90g (although it’s not clear whether that includes the pouch or not).

If you don’t need a valve core tool, a bottle opener, open wrenches, and every other part of the kitchen sink, the Spurcycle Tool won’t let you down. A great cycling tool kit with looks to match.

Price: $70.00

lezyne flow storage adapter

Lezyne Flow Storage Adapter

If your current storage solution is already packed, the Lezyne Flow will help you out. It’s a mount that goes right under your bottle cage and stores a V5 multitool, a CO2 inflator head, two CO2 cartridges, and two tire levers.

The V5 doesn’t have a whole lot, but it has the absolute essentials:

  • 3, 4, 5, 6mm hex wrenches
  • Phillips screwdriver

If you’re honest with yourself, how likely are you to need anything else when you’re not on an epic bikepacking tour?

If the answer is “not very,” the Flow Storage Adapter is a nice way to clean up your current on-bike storage situation.

Price: $50.00

fix it sticks multitool

Fix-It Sticks

Want to talk about light? How about 55g? That’s by far the lightest multitool you’ll find. Sure, it’s a bit limited:

  • 4, 5, 6mm hex wrenches
  • Torx T25

But again, how likely are you to need more than that? The Fix It Sticks work together to give you a good grip and up to 15nM of torque, and then disassemble to fit in your pocket. A must have addition to your bike tool kit list.

It’s the ultimate minimal solution.
