Vincero Design Water Bottle System
~click on image to see more~Vincero has been working on making it easier for cyclists to mate their water bottles to their bikes since 2008. By using rare earth magnets and a no drip squeeze valve, this minimal design keeps weight down and hydration up; it is also the system used by the 2011 Kenda Pro Team. Oh and they're 100% made in the USA.
