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

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.
