Great value multitool whose bulk makes it best for home not roadside use
B'Twin 300 Bike Multitool
8 10

Like other decent multitools, the B'Twin 300 Bike Multitool has a range of hard, chrome-vanadium steel tools that fold out from an aluminium body. There are nine tools: 2, 2.5, 3, 4, 5 and 6mm Allen keys, Phillips and flat-head screwdrivers, and a T25 Torx. What's special is the price: £6.50. For that, you might expect soft steel and a rattly tool body. Think again. This is as sturdy a multitool as I've ever used.

The tools are accurately made and tough. They pivot easily because of the nylon washers between them. And the multitool shows no sign of coming loose and falling apart. (You may need to tighten the pivot bolts at some point, of course.)

The aluminium tool body is comfortable in the hand, so it's easy to tighten or loosen stubborn bolts, such as a 6mm saddle clamp. At 87x47x15mm and 150g, it's relatively large and heavy for a multitool with nine functions. Leverage and durability are good, but it's a bit bulky for stuffing in a seatpack and will weigh down a jersey pocket. My 10-function Lezyne V10 is significantly smaller and two-thirds the weight despite also packing a chain splitter.

That V10 also costs four times as much as this B'Twin 300 Bike Multitool. Is it worth the extra? Yes. A chain splitter is a deal breaker when it comes to fixing roadside mechanicals. As chains get thinner to suit the growing number of cassette sprockets, breakages are becoming more common. Even if you're carrying a spare quick-link, you'll need to drive out a rivet or two so you can fit that. Size and weight, meanwhile, aren't just a matter for weight weenies. The smaller and lighter a multitool is, the more likely it is you'll have it with you on every ride. (Sod's law says you will most need the multitool that you forgot to bring.)

Having said that, if you're on a tight budget then saving pounds is probably more important than saving grams. If you don't mind a bit of extra heft and won't miss a chain splitter, you will not find a better value multitool than this. Where I think it will score for most road.cc readers is as a workshop multitool. It's a handy way to keep your most-used Allen keys and a few other tools together, and in the workshop its beefiness is an asset. That's where this test multitool now lives.

In the workshop, it's great – as good as any multitool I've used. At the roadside, it works okay but I begrudged taking it with me as there wasn't room in my seatpack after spare inner tube, tyre levers, patches, and quick link.

If it's too bulky to take on a ride then it's no use. Why use a multitool rather than separate allen keys when you are at home?
