So, there are different multitools. Finding the right one among these many bicycle tools is actually not that difficult. Here are a few questions that will lead you to the perfect tool:
Do I need a bicycle-specific multitool?
A multifunction tool from the hardware store is better than none at all. But if you buy one that is really made for bicycles, you will get much further with work on the bike! Here you then have tire tools or chain tools, screwdrivers, ring spanners, or a knife included. There are also special tools for camping and outdoor activities, and these are also quite interesting for some cyclists! Especially if you plan bikepacking tours , tent and campfire are of course on the agenda, and the appropriate tool in the bag!
A multifunction tool for bicycles, on the other hand, can help you in many life situations, it is not only practical when you have a bicycle breakdown! Parktool, Birzmann or Topeak make excellent tool sets for bicycles, with which you can also work on other things.
Which screws do you need to move on your bicycle?
There are no standards for the screws that hold a bicycle together. So if you want to know, which bits your multitool should have , a look at the screw connections you will work with can help. So take a look at your bike – do you need Torx and hex keys or rather flathead and Phillips screwdrivers? Do you need ring spanners? If you know this, you won't carry around unnecessary bits. The Torx T25 is becoming more and more the standard and is therefore included in most multitools.
Which multitool is better – individual parts or all-in-one?
Whether you get along better with a set of individual pieces or with many functions in one housing is purely a matter of taste. Individual pieces are more flexible and lighter. Many parts in one piece are more versatile and you can't lose anything. It's best to test and try out what you get along with better.
How much experience do you have?
Which multitool you should buy mainly depends on your skills . If you rarely work on your bike and prefer to leave major repairs to a workshop, a smaller tool with fewer functions may be sufficient. If you repair all kinds of bike breakdowns yourself on the go, your multitool can't be comprehensive enough. Even if you enjoy tinkering and want to gradually expand your knowledge, a multitool with many different functions is a good investment for the future.
Does your bike have weaknesses?
For some reason, does your bike chain keep breaking? Does your saddle keep sliding down? Have you been annoyed by a “flat tire” several times in the last few months? Then it absolutely makes sense to specifically prepare the tools and spare parts for it and always take them with you!
If you suspect that your bike really has a weakness, a thorough check at home or in the workshop can be worthwhile. Without wanting to offend you – your riding style can also be responsible for repeated breakdowns. If you repeatedly crash off the curb with a heavily loaded trekking bike, for example, it can cause tire blowouts. That's not a big deal, you just need to have tire levers, other suitable tools, and the necessary spare parts!
Which multitool do you need for an MTB?
There are few multitools specifically packed for MTBs. A tool with as many functions as possible usually saves your day in the bike park, no matter what error messages the bike produces. You can also do the screw check here to find out what you might need in case of an emergency.
Which multitool do you need for a road bike?
If you have a carbon road bike , a compact torque tool for on the go is a good choice because it won't damage your valuable bike on tour. Apart from that, the same applies here: Look at the connections on your bike, then you know what you can use to move them.
How do you store your multitool on the go?
Saddlebag, frame bag, bottle holder, or pocket – depending on where you want to transport your tool, the weight and size a role. If it is to travel in the pocket or backpack, a small, lightweight tool is practical, and it should also have no sharp edges. If you put it in the bike bag , a little more weight is not a big deal.
