What to Consider When Buying a Bike Multi Tool

If the 15 best bike multi-tool reviews don’t interest you or you still find it confusing on what to choose, here’s a little buying guide to help you take things to your own matter. We will be taking the vital factors that you must consider, these cover the number of functions, ergonomics, portability, whether or not it is easy to use, and durability.

Number Of Functions

  • Main Functions

The bike multi-tool’s main usage is to fix up loose bolts, connection points, raising your saddle, etc. And in order to do any of that, there are three main functions that you should look for.

First up is the hex key. Most of the bike can be disassembled by a 4mm or 5mm Allen key, some can be smaller like 2mm and 3mm. There are even some multi-tool that provide an 8mm and 10mm hex key like the Topeak PT30 but not a whole lot due to the fact that they don’t offer much leverage.

Second is the Torx Drivers. The majority of the tools will have a T25, sometimes a T30.

And finally screwdrivers. Philip head screwdriver will be common among the tools which is useful for derailleurs.

  • Additional Functions

There are some addons to the multi-tool that can be essential to some circumstances. Not all of the models have these functions, but they are handy and you might never know when you need them.

The chain breaker is important in case of a broken chain, bringing it back together easily cause you’re not going much far anywhere with loose chains. In this case, you will want to get the BLACKBURN Wayside Multi-Tool with its fantastic robust chain breaker and other additional features.

Secondly, a CO2 inflator in case of a flat tire. It’s a rare sight that a tool has this, but if you are looking for this one, the Lezyne RAP II 25 CO2 Multi Tool is splendid.

Finally, spoke wrenches to adjust the tension in the spokes of a tension-spoked wheel. You might as well get the Topeak Alien II with its excessive 31 functions containing 14G and 15G spoke wrenches.

Ergonomics

This one is optional but it’s better to have a good, comfortable grip of the tools while you are working on the problem. That’s where the Crank Brothers F15 comes in. You may find that it has a firm and pleasant hold, offering an easier experience.

Portability

Of course, being able to carry around for any situation is essential. Compact and lightweight design are keys here, that’s why the Wolf Tooth is a valid option due to the fact that it’s only 51g, can be stored inside the bike handle, and high-quality functions.

Easy To Use

Another thing is that the multi-tool is easy to handle and use. You will find that some tools don’t provide much leverage which in turn can cause inconvenience to use and are unable to get into hard-to-reach places. The BLACKBURN Wayside Multi-Tool got you covered, the quick link storage and removable keys make the fixing experience much more effortless.

Durability

Don’t forget to check what material the tool is made out of. Usually to make it more light, they will go with forged aluminum, more robust designs take different forms of steel. The Vibrelli Bike will be the most resilient bike multi-tool on the list, not being able to break down and falling apart easily.

Conclusion

After our selective review of the 15 best bicycle tool sets, the Topeak Alien II takes the cake for having the best overall performance, statistics that we have considered. A total of 31 functions to use in almost all of situations aside from fixing your bike.

Second place goes to the Crank Brothers Multi-19 with19 high-quality and precise functions and comfortable and firm knurled-edge grip
