Newton 20 function tool



A well-made multi-tool with just about every thing you need to assemble and adjust a modern bike

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

A well-made multi-tool with just about every thing you need to assemble and adjust a modern bike. As per usual, with so many facets, the Newton was a little cumbersome in the hand. Being made entirely from steel meant that flex was minimised, despite being quite wide. Not a tool that I would carry in my back pocket  though as I wouldn't fancy being run through by 14 different devices following a tumble.

It's good that Torx drives are included, not just for disc brakes but also for domestic appliances where bike tools are often deployed! I also got a warm feeling from the chain device, having saved more than one rider from a long walk home by removing their rear mech and turning their bike into a single speed - can't do that without a chain tool! It's not a bad one either - the handle doubles as a tyre lever in the same way that a spoon handle doubles as a tyre lever - badly.

The main issue is that for a big tool the actual keys are quite short, but they're decently made and function well. You can generate enough torque to do some serious work with it, it even managed to remove some pretty tight pedals. The slip-on 8mm Allen key will struggle with a crank bolt, and the spoke keys aren't great, but overall it's a good and useful selection.

I'd probably add a thick elastic band to it to keep unwanted keys from hindering the way - although a magnet keeps the chain tool from flapping about - and also find a bag to keep it clean and dry where possible. Other than that, all bases are covered.

Tools: Chain tool, 2/2.5/3/4/5/6/8mm Allen keys, 2mm L-shaped key, T10 and T25 Torx, 14g/15g spoke keys, flat/flat wide/Philips/Philips 2 screwdrivers, tyre lever, bottle opener.
