Cheap simple effective secure watertight tool holder; someone will tell you how to make one for free from an old bottle though

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.

The B'Twin Tool Bottle is a cheap, effective and dry way of carrying tools on your bike.

You can easily fit a spare tube, some tyre levers, a multi tool and some puncture patches in the 500ml hollow of the B'Twin Tool Bottle, with a little bit of room to spare for any other tiny tool preferences you may have, or some keys, or café cash, or lucky gonk. There's definitely enough room in there for the ride essentials. You might need to pad things out a bit with a bit of rag or something to stop all that rattling around, depending how snugly your bits and bobs fit together.

Once all your kipple's in the top screws down to keep everything secure and watertight, and slotted in a bottle-cage it will stay safe and unnoticed until you need it.

There are benefits to using a tool bottle over a saddle-bag to carry your kit. It's easier to get to stuff for starters. You can just hoik the bottle out of the cage and not deal with the faff of unstrapping a saddle-bag or fiddling about with bits while it's still under the saddle, watching things topple into the gutter, and then fingers-and-thumbs strapping it back on again. It's quicker to find the bits you need as the hole in the top is bigger and easier to access than that of your normal seat-pack. It's also a lot more waterproof, something those that have had to dry off the sodden contents of a saddle-bag after a five-hour wheel-spray soaking will appreciate. The downside is that it takes up space where a water bottle could be, troublesome if you like to double up on bottles, or have a frame-fit pump covering the other set of bosses.

You don't have to put the bottle on your bike though. It'll handily keep all your tools and bits clanking around in the bottom of your commute rucksack too, bruising your lunchtime banana.

The B'Twin Tool Bottle just works. It's a cheap as chips, simple way of carrying tools and spares, the screw-top lid isn't totally waterproof but rain and spray has to make an effort to worm its way in. Tidier than an old chopped water bottle.

Jo Burt has spent the majority of his life riding bikes, drawing bikes and writing about bikes. When he's not scribbling pictures for the whole gamut of cycling media he writes words about them for and when he's not doing either of those he's pedaling. Then in whatever spare minutes there are in between he's agonizing over getting his socks, cycling cap and bar-tape to coordinate just so. And is quietly disappointed that yours don't He rides and races road bikes a bit, cyclo-cross bikes a lot and mountainbikes a fair bit too. Would rather be up a mountain.
