Cycling essential item numero uno. Whether you need to adjust your saddle, tighten a bolt, or sort your chain out, a good multi-tool will be your friend in a time of need. Think of it as the Swiss army knife of the cycling world.

There’re lots of different options here, with various attachments like allen keys, screwdrivers, chain tools and wrenches. Pick one that suits the various nuts and bolts on your bike, and one that sits fairly flat in your pocket.

They can be a little weighty – particularly if you go for one with all the bells and whistles. If you’re going to stow in the back pockets of your jersey, you might want to pop it in the middle pocket or balance it out with items on the other side so it doesn’t pull your jersey round.
