Ideal for riders who want a light, good-looking bottle cage for road, gravel or everyday riding, with easy bottle access and standard frame-mount compatibility.
The ZEFAL Zéfal Pulse B2 is a straightforward upgrade for riders who want a bottle cage that looks tidy, feels light and doesn’t make bottle grabs awkward. At a claimed 30 g and independently measured at 31 g, it sits in that sweet spot where you get a genuinely lightweight cage without paying carbon money.
What stands out here is the bi-material construction. The reinforced centre section is there to keep the cage stable on the frame, while the more flexible outer sections help the bottle slide in and out smoothly. In use, that means a cage that’s easy to live with on everyday road rides, bunch rides, commuting and gravel, especially if you swap between standard bottles from different brands.
If you’re choosing between ultra-tight race cages and cheaper generic options, the Pulse B2 lands nicely in the middle. You get secure retention, easy access while riding, and a broad choice of 10 colours to suit your build. For most riders chasing low weight, simple fitment and dependable day-to-day use, it’s a smart bottle cage rather than an overbuilt one.
Bi-material cage body
A reinforced central structure adds support, while the outer sections stay light and flexible for smoother bottle entry and removal.
Low claimed weight
At 30 g, this is an easy way to trim weight without stepping up to a pricier carbon cage.
Proven easy access
The shape is designed to make bottle insertion and removal simple, which matters most when you’re grabbing a drink on the move.
Secure real-world retention
Long-form testing found it held bottles snugly and coped well with mixed surfaces, including gravel use.
Works with standard bottles
Designed to suit all standard bottles, so it’s a simple fit for most existing bidons you already own.
10 colour options
Available in a broad range of colours, making it easier to match your frame, bottles or team kit.
Mounting screws included
You’ve got what you need to bolt it straight onto standard bottle cage mounts.
Made in France
A good option for riders who value established European accessory design and manufacturing.

Bi-Material
We like this build because it balances support and ease of use. The reinforced centre keeps the cage stable and helps cut vibration, while the outer material stays light and flexible so getting your bottle in and out feels smoother.
Great for
Maybe not for
Fits frames with standard bottle cage bosses and is intended for standard cycling bottles. It’s a top-entry cage, so on very compact frames, some full-suspension bikes or small triangle gravel/MTB setups, check bottle clearance before buying. ZEFAL recommends lightly greasing the bolt threads and tightening moderately with a 4 mm hex key during installation.
vs Elite Custom Race Plus
A more retention-focused cage with a self-adjusting front section and a slightly heavier build. It suits riders who prioritise a firmer hold on rough roads and off-road terrain.
vs Tacx Ciro Bottle Cage
A close alternative in the same lightweight composite category, aimed at riders who want a snug hold and a sleek modern shape.
vs Lezyne Matrix Team Cage
A modern dual-side-loading cage that suits compact frames and riders who want easier access from either side.
Best match for standard bidons
This cage makes the most sense if you’re using regular cycling bottles rather than oversized lifestyle bottles. That keeps bottle access smooth and predictable.
Top-entry design needs frame clearance
On most road and gravel frames it’s a simple fit, but smaller frame sizes and some full-suspension bikes can benefit more from a side-entry cage if the bottle sits close to the top tube or shock.
Good balance of hold and usability
Some cages grip so tightly that mid-ride bottle grabs become annoying. This one is a better everyday choice if you want secure retention without having to wrestle the bottle out.
Worth greasing the bolts at install
A light film of grease on the cage bolts helps prevent seized threads and makes future removal much easier, especially if the bike sees wet weather or sweat.
