Ideal for road, commuter and fitness riders who want a light standard bottle cage with easy bottle access and a secure-enough hold for everyday riding.
The ZEFAL Pulse B2 is a classic full-entry bottle cage for riders who want a simple, clean-looking setup that doesn’t add unnecessary weight. At 30 g with a bi-component polyamide construction, it’s built to give you a firmer central structure for bottle support, while the outer sections stay more flexible for easier grab-and-go use. It suits riders who want a dependable cage for road, commuter and general fitness bikes without stepping into expensive carbon territory.
What we like here is the balance: the Pulse B2 is meant to make bottle insertion and removal easy, and that shows in ride testing where bottles were easy to grab on the move. Just as importantly, it still held bottles securely over rough, broken road surfaces. That makes it a good option if you value straightforward access more than an ultra-tight race-style grip.
It also helps that this cage works with standard bottles and includes mounting screws in the box, so it’s an easy upgrade for most bikes with regular bottle bosses. The lower slotted mount seen in review coverage can also offer a little fitment tolerance on some frames. If you want a cage that’s light, practical and colour-matched to your bike, this is a very easy one to recommend.

Bi-Material
We get a smart balance of support and usability here: a more rigid central structure helps cut vibration and hold your bottle securely, while the outer material stays lighter and more flexible for easier access.
Bi-component polyamide
This two-part polyamide construction is designed to blend strength with flexibility, so you get dependable bottle retention without making bottle insertion and removal awkward.
Great for
Maybe not for
Fits standard bottle cage bosses and is designed for standard cycling bottles. It is a traditional top-entry cage, so on smaller frames or bikes with frame bags, check vertical clearance before buying. Mount with a 4 mm hex key and apply a light grease to the bolt threads during installation.
vs Tacx Deva bottle cage
A close rival if you want a similarly light composite cage with lots of colour options, but it is known for a firmer bottle grip.
vs Elite Custom Race
A long-running benchmark in performance bottle cages, with a self-adjusting grip system aimed at different bottle diameters and smaller frame clearances.
vs Topeak Ninja Master+ Cage Z
A practical alternative for riders who want a bottle cage that can also carry add-on tool or storage accessories underneath.
Best if you value access over an ultra-tight grip
This is the sort of cage we’d suggest to riders who want to grab and replace a bottle easily while riding, rather than wrestle with a super-firm race cage.
Check frame clearance on compact bikes
Because it’s a standard top-entry design, smaller road frames, full-suspension bikes and bikes running a frame bag can sometimes suit a side-entry cage better.
Standard bottles work best
It’s designed around standard cycling bidons, so if you mainly use oversized insulated bottles or non-cycling drink bottles, measure first rather than guessing.
A smart everyday upgrade
For commuters and recreational riders, this gives you a noticeably nicer feel than a bargain cage while staying light and easy to live with.
