Up to +11 watts. Buy it for aero gains, with a bonus of extra hydration. Results from real-world aero tests by Jim Manton at Fast or Fiction, ERO Sports are below.
The BackBottle's main benefit is SPEED. By smoothing airflow behind the rider we have seen up to +11 watt improvements with tight jerseys. Great for carrying extra water, but REALLY GREAT for extra speed!
Made in the USA
100% made in the USA with BPA free plastic. Lightweight and versatile the bottle was designed to compliment long rides to be used along with your frame bottles. The unlock for BackBottle came once we got it aero tested - it blew us and the testing group away.
