Zefal Pulse B2 Bottle Cage



A decently priced, lightweight cage that'll hold your bottle snug

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.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

  • Exceptional
  • Excellent
  • Very Good

  • Appalling

The Zefal Pulse B2 bottle cage is light, easy to use and offers excellent drink retention for not a lot of cash. It comes in a range of colours too, so you can tie it in with your bike's paintjob.

  • Pros: Works with a range of bottle sizes, easy to add and remove bottles
  • Cons: None really... you can buy cheaper bottle cages

The Pulse B2 is manufactured using two different materials: a reinforced composite structure for the main body, which brings strength and rigidity to the mix, and a technopolymer resin for the 'wings' to offer some flexibility to allow for different bottle sizes.

For most of the test period I used the Zefal on a Pinarello Grevil gravel test bike, and smashing it over the local trails saw no issues with bottles flying out, even on the fast sections.

There is a lot of flex at the extremities of the cage to clamp the bottle in place, which means you can use bottles of different diameters. I've got quite a collection of brands in the cupboard that vary in diameter and they all stayed put.

The spring in the outer body means that inserting and removing the bottle is easily defined, with just a firm grasp to withdraw it and a bit of force to relocate it.

With a circular hole for the top bolt and a slot for the bottom one, there is some adjustment for fitment to your frame in case the bolts are slightly out, although most bikes don't really need it.

On the whole, it is a quality bit of kit. It seems well made and durable plus I like the shape. It comes in a range of 10 colours, too: blue, green, yellow, orange, red, dark blue, black, grey, white and pink, all with black inserts and graphics.

At 31g it's also pretty light.

As for value, you can get this style of bottle cage for around six quid in various places over the internet, but when you compare the rrp to others we've tested it isn't bad value for money and they always make more sense than carbon fibre when it comes to pounds per gram.

The Tacx Ciro is a similar cage with plenty of colour options and comes in at £15.99, while something like the Vel Race Cage weighs the same and does a decent job too for £11.99.

Overall, the Zefal is the right ball park when it comes to price and weight, plus it does a very good job of keeping your bottle in check.

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, "With innovative construction, the Pulse B2 bottle cage combines two materials with distinct properties. The centre of the reinforced composite structure brings the necessary rigidity to reduce vibrations and ensure excellent bottle retention while the technopolymer resin offers flexibility and lustre to the bottle cage to facilitate its use."

It's an all-round decent bottle cage for the money.

Use this box to explain your overall score

Nothing groundbreaking in terms of weight or price against a lot of the opposition, but it looks good and does its job very well. It's easily a 7, but I think its ability to hold a variety of sizes securely nudges it up to an 8.

Overall rating: 8/10

As part of the Tech Hub here at F-At Digital, our senior product reviewer Stu uses the knowledge gained from putting well over a 1,000 products through their paces (including hundreds of bikes) to write in-depth reviews of a huge range of kit. After first throwing his leg over a race bike back in 2000, Stu's ridden more than 160,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him he still likes to smash the pedals rather than take things easy. Although, as he spends a fair bit of his time reviewing ebikes these days he's becoming an expert in letting the motor take the strain. He's also waiting for 23mm race tyres to make a comeback!
