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 Zefal Pulse Z2 bottle cage offers loads of adjustability for small frames and holds your bottle securely, regardless of the terrain. It isn't a true side-opener, more of an angle, but still works well where space is limited, though you might struggle with larger bottles.

Some cages let you literally insert a bottle sideways, like the Arundel STR DTR Side-Entry, which is perfect if you have no access to get the bottle in from the top, like with a traditional cage. The Zefal's design differs slightly; its reinforced fibre-glass material is too taut to force a bottle in directly from the side, but the shape means you can slide it in from quite an angle, which should still enable you to use it with a small frame or a larger one loaded with a frame bag.

On a compact style gravel bike with a frame bag fitted I could easily fit a 500ml bottle into it, while a 750ml was just a little bit of a squeeze. Once in, though, both sizes of bottle were held firmly, even when full on really rough terrain.

The outside of the cage has a hardwearing matt finish, while the inside has a polished look to it which helps your bottles slide in and out easily.

The Pulse comes in two parts, which allows you to switch the upper bit to either left or right loading, plus you get plenty of adjustment for the bolt holes so you can customise how high up the seat tube or down tube you want it to sit.

It costs £11.99, which is pretty good value when compared to the similar Tacx Radar cage at £13.99. It's only a couple of quid, admittedly, but the Pulse looks a much more refined product.

Overall, the Zefal Pulse Z2 is a good looking cage that offers very firm bottle retention.

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?

Zefal says, "Do you have an enduro MTB or an electric MTB that doesn't have space for a bottle cage? Or are you looking for a better way of transporting your bottle on a Gravel bike equipped with Bikepacking? The Pulse Z2 is the ideal bottle cage for these scenarios. It features a right or left-side opening for easy access and is made from a fibre-glass material. This bottle cage boasts all the technical characteristics needed to ensure the bottle is held in place during even the most strenuous rides."

Once it has hold of the bottle it isn't going anywhere.

It won't work on really small frames, especially with big bottles.

Not as svelte looking but they do one called the Wiiz with similar semi-side entry functionality although wrapping round the bottle a little further  that you can pick up for a fiver. I've used them for thousands of off-road km without issue.
