600 ml bottle for cageless magnetic-mechanical mounting system With the magnet-mechanical bottle holder system, the TWIST bottle 600 revolutionised the bicycle bottle. The overmoulding, which has now been improved even further, enables an ultrasecure connection between the bottle and the bike – without the need for a gravity kit! With the new design of the TWIST bottle 600 comes not only a new print. The lid is now also compatible with the other bottles. And thanks to the even softer material, the new TWIST bottle 600 is even easier to squeeze.
