The best Allen keys and multi-tools for 2019
All cyclists will need to make adjustments at some point - it's a good idea to have a reliable set of Allen keys at home, and a multi-tool to pop in your pocket for the ride
The vast majority of bike adjustments are made using an Allen key. At home, it’s best to use a full sized tool – as the likelihood of rounding a bolt is reduced, but whilst on the go, most cyclists carry a multi-tool in their jersey pocket or saddle bag.
Allen, or hex, key sets vary in quality. Spend more and you’ll enjoy a snug fit, reducing the chance of damage to the bolt. Those with a ‘T’ or ‘P’ handle as opposed to the standard ‘L’ shape allow greater grip on the handle, and you cal also get ‘three way’ versions with three sizes on one handle.
An Allen key set is not the same as a Torque wrench – which you use to ensure the bolt is tight enough without putting too much stress on the component in question.
Some bolts use a star shaped Torx head, which requires Torx keys – though these are slightly less common.
Multi-tools vary dramatically in size, weight and price. Some riders prefer to carry just a couple of tools in a small, lightweight package, whilst others would rather take a more hefty tool with almost every potential get-out-of-jail free card to hand.

What
Like a Swiss Army knife, a good cycling multi-tool should allow you to effectively deal with any maintenance issues you might have whilst out on a ride or even as a do-it-all workshop tool.
A well made and thought out multi-tool should be practical enough to enable the use of all the features and not have ‘token’ features. They should be comfortable in use and the tools of sufficient quality so as to not damage precious parts.
Why
A good multi-tool will accompany you on all of your rides so needs to be reliable. You should be able to practically strip a bike down completely using one so it should include all of the correct sized Allen keys and Torx keys required for modern bikes along with others such as screwdriver heads or a chaintool and not have anything obsolete or impractically sized.
How
The cycling multi-tools were used for a variety of tasks both out on rides and in the workshop to check functionality, ease of use, comfort, weight, and durability.
Key Features
- Practicality – there is no point having 20 different functions on the multitool if they cannot be used properly.
- Versatility – a good cycling multi-tool should be allow you to fix most mechanical issues whilst out on a ride.
- Durability – The tools should be strong enough to withstand repeated use and not fail you when needed most.
