The Magnum bottle's 975 ml capacity makes it possible to carry large amounts of drink for long rides. The shape of the Magnum is designed to be compatible with most bottle cages (Zéfal or other brands). Its over-moulded cover offers better grip on the bottle and its double-closure Pro-Cap system makes it 100% watertight for easier carrying. No more spilled drink on the bottle and on the bike! The silicon push offers a pleasant sensation when drinking. The quick-opening valve provides better-regulated control of the liquid consumed without spillage due to overflow.
