Obsession & Innovation. Probably the two words that best decribe Cannondale's committment to their road bike line-up. Widely acknowledged as the best in the business when it comes to aluminum, they continue to refine their frames - shaping and butting tubes to extract every last ounce of performance; Cannondale never follows, they continually push the limits of carbon fiber technology with their Six/13 and, now, the Synapse, SystemSix, and SuperSix performance bikes. Amazing machines from an amazing company.
