Why are some of BMC’s sponsored pros choosing the Racemaster over the company’s full-carbon, top-of-the-line Pro Machine? Because the Racemaster’s stiff, atavistic aluminum bottom half delivers off-the-charts efficiency, while the carbon top half mutes the attendant vibrations. “I love this bike over all others!” gushed one tester. “Great design,” said another. “BMC has its own look, and it stands out.” It’s not exactly cheap, but the componentsincluding full Ultegra SL and fast-spinning Fulcrum Racing 5 wheelsare worthy of the price. $4,495; 17.4 lbs (56cm); bmc-racing.com
