The Zefal Magnum Pro Water Bottles are made for riders who don’t want to run dry halfway through a ride. Each bottle holds almost a litre, giving you enough hydration for endurance rides, warm-weather training, or long commutes. The Pro-Cap design keeps every drop sealed in your bottle, not on your frame or in your bag.

When you’re pushing distance or riding in the heat, the extra capacity makes a real difference. These bottles fit most standard cages, so you can top up your setup without needing any special mounts. The soft silicone push valve feels smooth to drink from and gives controlled flow — no messy splashes or wasted drops.

Who is this for?

Ideal for riders who spend hours on the road or trail and want fewer refill stops. Perfect for touring cyclists, endurance riders, commuters covering long distances, or anyone who prefers to carry extra hydration rather than rely on café stops.

Who is this not for?

Not the best choice if you prefer compact bottles or have smaller frames with tight cage clearances. The Magnum’s wider body may not fit some closed-style cages – in those cases, an open cage like the Zefal Pulse B2 works best.

Why we love it

We’ve found the Magnum Pro strikes the right balance between size and usability. The grip feels secure even with sweaty hands, and the Pro-Cap system really does prevent leaks. It’s a straightforward, high-volume bottle that does its job well — which is exactly what you want on a long ride.

Hot tip!

Pair these with open bottle cages for an easy fit. If you’re heading out on a hot day, fill them halfway, freeze overnight, then top up before riding — the thick walls help keep your drink cool longer than a standard bottle.
