The Elite Super Corsa MTB 750ml Bottle is built with a 74mm diameter allowing for use with all conventional bottle cages on the market, making it perfect for riding. A protective valve cover also keeps it clean from mud & dust. The slightly narrower body with a series of rings facilitates a simple grip, providing an easy grasp & opening of the bottle in all conditions, while a large opening enables quick filling of energy supplements. In addition, the Super Corsa is 100% biodegradable as it is made with 100% corn based plastic, making a perfect eco-friendly re-usable alternative.
