Buyer’s Guide

The ability to make minor adjustments and unexpected repairs on the field can save you from a long walk home and for that, a well-rounded multitool is an essential item to keep with you at all times. But what exactly qualifies for a good multitool? The response varies from person to person but a key set of features and considerations are common to all. This buyer’s guide will give you a basic overview of the features you can get in a quality multitool along with some important considerations to keep in mind when in the market to buy a multitool for your MTB.

Key Features

A multitool for mountain bike may differ from the one used for general purposes, so it’s important to familiarize yourself with the key features and functions to look for in your purchase. You can either go minimalist and only look for the absolute minimum features to fix the most occurring issues or go versatile to deal with complex repairs as well. Here are some of the features you should be looking for in a biking multitool.

Hex Keys

Hex keys, also known as Allen wrenches, are a must-have in your multitool kit as they are commonly used for repairs and adjustments of all sorts. There are multiple sizes of ​allen keys available, but it is advisable to pick a multitool that has at least 4 to 5 different sizes of hex wrenches to allow for adjusting the various parts of your mountain bike. 

Screwdrivers

A screwdriver is an absolute must no matter what task you have at your hands. Most MTB make use of both crosshead and flathead screws and hence, both types of screwdrivers are necessary to cater to any emergencies. You should also look for a multitool with multiple sizes of screwdrivers to make any adjustment and repairs when out in the woods.

Torx Drivers

Gone are the days when T25 and T30 Torx screws were only used for holding disc brakes in places in mountain bikes. Since they not easily loosened from day-to-day vibrations or even in high-impact accidents, Torx screws are becoming increasingly common in MTBs. Thus, Torx drivers are an important feature of a good multitool and are specially designed to allow for a greater torque application on the screw. T25 is the standard size, but T10 and T30 can also come in handy in case of emergencies.

Chain Splitters

The occurrence of a broken chain can undoubtedly stop you dead in the track and in such cases, chain splitters or chain breaker are a necessary tool to have. ​A chain breaker is used to dismantle broken chain links so that the chain can be repaired or fixed if you ever land into an emergency during long riding sessions. However, make sure to check if the multitool chain ​breaker is compatible with the bike chain.

Tire Levers

Tire levers in multitools are either molded in the tool body or attached separately to allow for fast and efficient tire removal, repair and replacement. It’s recommended to look for slightly longer plastic and composite levers to achieve a greater torque and make the job easier.

Spoke Keys/Wrenches

These are required to fine-tune the spokes of the bike wheels and bring the wheels back to a perfect circle. Narrower spoke wrenches can easily fit in tight spaces and can be turned quite effortlessly to tighten or loosen up the spokes and straighten buckled wheels.

Blades

Quality knife blades are required in situations in which you need a cutting tool for scrapping or wire peeling. And if you plan on going for long biking sessions in the woods, having a multitool with short yet sharp blades becomes even more important.

Other Considerations

Quality

You can have all the features in your bike multitool but if it’s not of the right quality, the multitool is of no use. In fact, it might damage the bike and injure you or even break the first time you use it. Hence, it’s crucial to invest your money in a multitool of high quality.

Size And Weight

Many people tend to overlook the aspects of size and weight which ultimately results in a poor experience. While a lighter weight is desirable for ease of handling, make sure not to compromise on the durability since the tools need to be sturdy and reliable when you’re stuck in the middle of nowhere. Moreover, ensure that the size of the multitool allows for enough leverage or otherwise, you will have a hard time to even screw a nut tightly. 

Storage

Most manufacturers are now focusing on designing compact and portable multitools so that riders can carry them around easily. Special multitool casings provide extra protection but may add on unnecessary weight which might be undesirable for some people. Compact multi tool kits can also be carried in your backpack or the bike's saddlebag.

Conclusion

Every mountain biking enthusiast needs a quality multitool kit at one point or another as it allows you to perform all the common fixes and repairs, even when you’re out in the woods. From adjusting handlebars and brakes to tightening loose bolts, a multitool kit might be all you need to save yourself from a lot of hassle. We hope that this buyers guide will help you find the best mountain bike multi tool available in the market according to your biking style and needs. ​Ensure to go through our list of top-picks to further narrow down your options and have an amazing, hassle-free experience.
