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 Topeak Ninja Master+ Cage Z is reasonably light, very competitively priced and easy to get bottles in and out of, and although its grip proved entirely secure during the test, its gentle-feeling squeeze doesn't inspire confidence.

The Ninja Master series of parts from Topeak gives the ability to add on extra carrying capacity to the humble bottle cage. The accessories fit into a bottom section with options available that include toolboxes, small enclosed zipped cases such as the Roadbox and a C02 Fuelpack which holds two 16g cartridges and the inflator valve.

This cage is plastic and weighs in at a very respectable 35 grams without bolts or accessories, which makes it a very competitive weight. Bottles are easy to place in and remove as there is a significant amount of flex in the arms – in fact, the pressure exerted on the bottle is not great.

> Cycling hydration: Is 1 water bottle or 2 best on long rides?

While testing I have not had any bottles eject while riding, but I was always wary and kept checking.

I was especially wary with this on my mountain bike and avoided trying it on the roughest trails for fear of losing the bottle, but to be fair it worked perfectly well on regular rough stuff.


At £7.99 it is good value and at the lower end of the price range. In fact, the Zefal Pulse A2 is one of only a few we've tested that can match it on price, though Topeak's own Ninja Master+ Cage SK+ is only £2 more and Stu found it very secure, with the flex having the opposite effect of making bottles tricky to quickly remove.

The Lezyne Flow bottle cage isn't that much more either at a current price of £11.50, and gives a much stronger hold.


The Cage Z is a perfectly good if rather flexy cage at an attractive price. It doesn't give your bottles the strongest squeeze, which may worry some over very rough terrain, but for road and even gentle off-road use it proves perfectly secure.

Tell us what you particularly disliked about the product

The flex makes me fear a bottle would fall out while riding, though that never happened, even off-road.

How does the price compare to that of similar products in the market, including ones recently tested on

The Ninja Master+ Cage Z is one of the cheaper bottle cages on the market – the Zefal Pulse A2 is one of the few we've tested at a similar price.

Did you enjoy using the product? I did worry about bottles falling out and was repeatedly checking, though none did

Would you consider buying the product? No

Would you recommend the product to a friend? Perhaps road riders

Use this box to explain your overall score

While this worked fine on the road and on medium-rough off road routes, the ability to attach accessories is a clever feature, the flexiness may lead some people to worry about bottles staying in on very rough ground. To be clear I never lost one, but it didn't make me feel confident.
