Bottle Rocket

Bottle Rocket

Bottle Rocket’s unique design conveniently secures any standard bike water bottle between your aero bars for quick and safe access. And, it’s placed in the most aerodynamic position according to studies conducted by Cervelo and others, thus actually creating negative drag–and in effect negative weight– to your setup.

Lodging Accommodations

Stay just a few miles away from the event venue and enjoy a free hot breakfast before your race!

Your organization is making a difference and I’m glad I have been able to be a part of it!

I liked how smooth the race itself was. I never felt as though I did not know what was going on or what to do next.
