At road.cc 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 road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
An ant's jaw. Huh? That's what Arundel reckon their Mandible bottle cage is like. It's strong but light. Like an ant's jaw.
At 28g, the Mandible is certainly light. They manage to make it so light because the core is foam. I hunted around the garage and weighed a bunch of other bottle cages. A standard alloy cage is about 48- 56g (who knew?) so chances are you'll be saving a few grams here. If you run two bottle cages, and swap to two of these, you might save 50g or something like that. In the overall scheme of things, that's not a big deal but if you're a weight weenie and every gram counts, well, here you go.
Obviously, that foam core affects the strength? Well, no, not in a bad way. Those arms that look so delicate grab your water bottle in a bear hug and hold it firm. Combined with the lip at the top, they'll keep the bottle in place over rough roads or even off-road trails. I tried it on some dodgy old tracks skirting Salisbury Plain where I've lost bottles before and it was absolutely fine.
So, it's lightweight and it works, and that's yer lot. Oh, and you get the choice of two different mount positions. And it looks cool whether you go for this matte version, the gloss black or the white. In terms of price, it's not out of line for what you'd expect to pay for a carbon bottle cage. As a comparison, the Blackburn Camber I tested last year has a list price of £39.99 and was virtually the same weight. However, we're guessing that if you are already in the market for a carbon cage, a fiver either way isn't going to make much difference to your choice. Weight, looks and grip are; and the Mandible certainly scores well on all of those.
Very lightweight carbon cage that holds your bottle ultra-secure

Make and model: Arundel Mandible Bottle Cage
Size tested: Black
Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
Well, it's for people who want to shave off every gram possible.
Arundel say, "You don't have to ride 5 hours a day to qualify to buy a Mandible cage, but it's designed for those who do."
Tell us some more about the technical aspects of the product?
There's not a great deal of technology in a bottle cage but Arundel have made this with a foam core to keep the weight as low as possible without sacrificing strength.
It's a hard one to mark. With a bottle cage, it either holds your bottle firm or it doesn't. This one does whatever the surface/terrain.
It's so strong that you'd have to try really hard to break this thing.
I have a Blackburn Camber carbon-fibre bottle cage that's the same weight, but this is about half the weight of a standard alloy cage.
Most carbon bottle cages are £35 and upwards. This is among the more expensive although it's also incredibly strong.
Of course, if you're just after the best value you can get, you can use a cheap alloy cage for a fiver. That's fine. But if you feel like indulging yourself with something that works very well, this is a good option.
Plus, I think it looks cool. I like stuff that looks cool.
