Fly Elite The Elite Fly is WorldTour’s most used water bottle because it’s incredibly lightweight. It’s the world’s lightest bottle. Its record weight (at only 54g for the 550 ml version) makes it possible for us to use less plastic material as we make it, and guarantee the Elite-classic ergonomic structure that it's easy to squeeze so liquid flow is abundant with the lightest pressure. Fly Elite is available in many different colour options for a perfect match with your bike and your bottle cage.
