A strong choice for endurance riders, bikepackers, commuters and anyone who needs close to a litre of water between refill points.
The ZEFAL Magnum Pro is a premium high-capacity cycling bottle designed for riders who would rather carry extra water than stop for a refill. With 975 ml / 33 oz capacity, it is well suited to long-distance riding, hot conditions and routes where water points are limited. The polypropylene construction is BPA-free, odourless and designed to keep water clean and pure.
The Pro-Cap double-closure system is 100% watertight when closed, helping prevent leaks in your frame or kit bag. Open it on the move and the quick-opening valve delivers a controlled flow without overflow, while the soft food-grade silicone nozzle provides a comfortable drinking feel. An over-moulded cover and grip ring make the bottle easier to remove, hold and use while riding.
The Magnum Pro fits most ZEFAL and other-brand bottle cages, but its 76 mm diameter means it may be slightly too wide for some closed cages. For the most reliable fit, use an open cage and ensure the bottle sits firmly against the cage’s bottom stop, with the top stop positioned at the bottle’s narrowing. It is dishwasher safe and has a wide mouth with a hand-removable nozzle for straightforward cleaning.
