The Zéfal Z Box L is a tool holder for longer rides, and it does exactly as it claims with aplomb.

Made from hard-wearing and durable polypropelene, the Z Box L is designed to keep all your spares and tools in one waterproof place, and provides a generous 0.8L in which to do it. On our test rides it didn't rain, so we tested its waterproofness by submerging it under water for a few minutes with various bits and pieces inside. There was no noticeable leakage whatsoever.

For a storage device the Z Box L is also surprisingly flexible, coming with two compartments: a larger base and a screw-on appendage that either provides a smaller secondary compartment with the separator left in, or greater capacity up to the full 0.8L with the separater taken out. This means you don't have to lug the full 0.8L of space around with you on your rides if you're struggling to fill it, but also provides handy extra space for food and cash (or rubbish!), should you find your jersey pockets too small to carry all you need.

The only potential criticism at this point is that it doesn't come with vertical compartments within the two sections, something that might appeal if you like to keep your tools, spares and anything else more organised.

Naturally, the Z Box L fits into a standard size bottle cage, and does so very snugly thanks to a dimple in the large compartment that helps it sit flush in most cages – so annoying rattling isn't a concern so long as you haven't left lots of space inside for your equipment to move around.

As a looker, it's never going to set the world alight, but it does resemble a bottle when in place – and if we're honest that's all we're looking for from it. You'll also find Zéfal logos and branding embossed in black, but handily they don't conflict obviously with other branded kit you might be carrying on the bike because of the black-on-black colourway.

Thanks to its ability to keep the elements out and sit largely unnoticed in your spare bottle cage, the Z Box L is £6.99 well spent if what you need is extra-solid and dependable storage.

If you're out on a longer ride, wouldn't you need the second bottle cage for water?

Not necessarily

I use a Pro tools 750ml tool bottle in one cage and a 1000ml water bottle in the other cage for rides up to 75 miles

Anything over that then i also carry a 500ml Oasis,Coke,Pepsi (whatever is to hand) bottle in my jersey

Once ive drunk 500ml out of the 1000ml bottle i top it up from the 500ml bottle and throw it in the nearest bin

If anymore fluid is required then i have two high 5 tablets in the tool bottle so its just a case of finding a friendly pub/shop/person to fill my bottle up

Spare tablets in your kit are very useful.
