In life most individuals try to prepare for any hard times that may come their way. As cyclists, we must also prepare for anything that might happen while we are out riding. When it comes to fixing any minor problems with your bike, you can’t go wrong by carrying a bike multi tool with you. The best bike multi tool can mean the difference between riding smoothly or carrying your bike back home.

So what is a bike multi tool? They look very similar to a standard utility knife, but are a little wider and fit more tools. A standard bike multi tool will come with Allen Hex keys, a Phillips screw driver and a Torx key. Every bike’s standard adjusting and tuning needs revolve around these tools and a few others.

Different Bike Multi Tool

Let’s take a deeper look into how owning a bike multi tool can really add to your biking excursions.

Making Adjustments

If you rely on your bike for transportation or just for weekend get aways then you should familiarize yourself on how to handle some minor maintenance and repair. Below are some basic repairs that will come up when you ride and what tools are needed to fix.

  • Adjustments – If you are receiving a new bike or just need to make some adjustments on a current one, then you will need to have some Allen hex keys handy. You should loosen the screw in your seat to lift it up or down for height adjustment or to tilt it forward or backwards. The same concept is used when adjusting the handle bars.
  • Disc Brakes – When tampering with your brakes, it requires a Torx key to remove the bolts. Not to be confused with the above mentioned Hex key, which is shaped like a 6-sided hexagon, the Torx key is a six-sided star shape. A T25 socket wrench is also a great addition to have to take care of your disc pads.
  • Accessories – When installing or taking off your accessories you will need a wrench. Most items such as fenders and racks are held on by nuts and bolts. An open wrench is a good tool to keep on hand for maintaining and tightening the nuts and bolts. Some multi tools will offer different sized wrenches to fit various nuts.
  • Tires – A tire lever is a must-have in case your tire becomes loose or needs to be removed altogether. While it’s a stand alone tool, some multi tools will have a smaller version of it. You can choose between a plastic or metal version. Some prefer the plastic because it does not scrape or leave harsh marks on your rims. Others prefer the metal because it has better leverage and durability.
  • Chain – You will need a chain tool which will make fixing and adding links and pins to your chain much easier. This is also a stand alone item, but some manufacturers will add a smaller version into multitools for convenience. Also there is a chain breaker you can use if you get into a sticky situation. This specialized tool breaks the chain in a way that it can be easily mended with the chain tool.

Maintaining your Bike

Experts highly suggest that you do a 6-month or yearly maintenance on your bike, whether you use it daily or only on the weekends. When your bike is properly maintained then it keeps a high safety rating and you can avoid any damages that could occur that lead to you being stranded while riding. You could take your bike to a shop and have a mechanic work on it, but more of the tasks are fairly simple and you could save money by doing it yourself. There are a few guidelines when you decide to take this route.

  • Don’t cut corners – This refers to what your bike maintenance calls for and what’s cheapest or easiest to find. Take the time to find the right sizes or special lubricants for bike chains, versus using household or motor oils that will get sticky and attract debris that wears out a chain fast.
  • Work in a well-ventilated area – If you will be using any lubricants or sprays to clean or maintain your bike, then it’s better to do this outside or in a well-ventilated garage. Some sprays or lubricants can give off an odor that can make you nauseous, dizzy or make your head ache.
  • Wear gloves – Whenever you are cleaning or using tools on something, it is a good idea to wear gloves to protect your hands from cuts and chemicals. Especially if you will be working with the bike chain, slip on a light pair of gloves for protection.
  • Keep it clean – When you are lubricating parts such as the chain or your brakes, be sure not to use too much that it drips on other parts, especially your wheels and rims. Lubricant on the wheels can affect your brakes, cause them to fail, and potentially lead to a crash.
  • Not too tight – After adjusting or cleaning, make sure all nuts, bolts and screws are put back on tight, but not too tight. You don’t want to strip away the screws. Turn until you feel resistance and make sure the bolt is not poking out unnaturally.
  • Cover – When you aren’t riding your bike, the best maintenance you can perform is to keep it sheltered from the elements. Bike parts are easily prone to rust which can damage it. Keep your bike inside, in a shed or simply under a tarp. The drier it stays the better you can fend off rust.

Wearing gloves during bike maintenance

Now that you are ready to get hands on with your bike, here is a list of some simple bike maintenance tasks that you can do yourself to keep your bike road ready. If you are very unfamiliar but eager to learn, then you can look up popular websites for how to videos to get you pointed in the right direction.

  • Remove, clean and re-lubricate chain and gears.
  • Re-lubricate and check brakes and gear cables.
  • Take apart, clean and re-grease headset.
  • Take apart, clean and re-grease front and back hubs.
  • Clean cluster with a solvent dampened cloth.
  • Check handlebars and head stem for and unnecessary movement.

What’s Available?

Before shopping take a few moments to look over all the nuts, bolts and screws on your bike. Figure out what size hex keys, wrenches and Torx keys you will need to fix or adjust each item. This will give you a better idea of what to look for and can help weed out some multi tools that don’t provide the sizes or tools you need. If you’re not sure, look at products that offer various sizes of the aforementioned tools so you’re guaranteed to have one that fits. Now on to the reviews.
