BMC Team Machine SLR01/Shimano Ultegra Di2 Complete Bike - 2012 - $4,499.00

From podiums at the brutal Spring Classics, to stage and single day race wins across North America and Europe, oh, and that grand tour victory in the summer of 2011. While less the industry's best-kept secret as it once was, the rapidly growing palmares of the BMC Team Machine SLR01 are as impressive as they are varied. There are very few frames in the professional peloton that can claim emphatic dominance over cobblestones and hors categorie climbs under climbers and sprinters alike, but that's the inherent beauty of the SLR01. It's the result of calculated Swiss engineering that makes this bike an absolute blast to race at every point in the season. Lightness and durability; comfort and stiffness -- when it comes to frame design, aren't they opposites' All too true. Which is why BMC had to re-evaluate their choices in materials and entirely re-think their tubing shapes and configurations. In order to give the frame damping where desired and flex-resistance where required, they applied stepped tube profiles, all-new carbon fiber alignments, and material compositions. High modulus layers of carbon are used where stiffness is desired, high strength layers are used where loads are heaviest, and high elasticity layers were used where compliance was needed. This lengthy project of optimizing the overall ride quality of the Team Machine SLR01 came to be known as their Tuned Compliance Concept, or TCC. Where does BMC's TCC work make the biggest impact on the Team Machine SLR01' It's most evident in three areas. First is the seatstays. Their slender profile from the brake bridge down to the dropouts is reminiscent of the design you'll find on the Cervelo R3 and the Ridley Excalibur, where these stays act as leaf springs to provide vertical compliance. But above the brake bridge the stays are beefy to serve as a solid foundation for vibration-free braking. - $4,499.00
