Race Machine RM01/Shimano Ultegra Di2 Complete Bike - 2012

The combination of Shimano's Ultegra Di2 gruppo with BMC's Race Machine RM01 results in a performance bicycle that can dominate the local crit circuit or catapult you to the KOM on your next gran fondo. While the Team Machine represents the pinnacle of BMC's offerings, the BMC Race Machine RM01/Shimano Ultegra Di2 Complete offers the greatest performance return per investment dollar.

Designed for racing, the RM01 puts you in a powerful and efficient aerodynamic position. This also means it has a carefully designed carbon layup that ensures low weight, strength, and stiffness where you want it. A mix of high-modulus and high-tensile material perfectly balance strength, durability, and weight. High-modulus is strong and stiff, but relatively brittle. So BMC mixes in lower modulus, high-tensile fiber to add durability. Together, it creates a bike frame that possesses all the right characteristics.

As stability is paramount to BMC, they use a tapered 1-1/8in to 1-1/4in steerer tube. This lends stiffness for stability through high-speed turns and on rough pavement, but it's still comfortable because of BMC's Tuned Compliance Concept (TCC). BMC engineers created zones in the fork legs where the material and shapes are selected to provide a degree of compliance, while maintaining the torsional and lateral stiffness you need for uncompromising performance and precise steering. The RM01 seatpost also features their Tuned Compliance Concept. In other words, the Race Machine is easy on your body in the bumps, but still extremely stiff when cranking out the watts .

One feature you can't miss on the RM01 is the Integrated Skeleton Concept (ISC) at the seat tube junction. While some might see it as an aesthetic flair, the truth is there's a strong practical reason for it. Advanced computer analysis allows BMC to fine tune both the shapes and the layup to maximize stiffness while minimizing weight. Continuing this fixation with optimization, all the cables are run externally, which is lighter and provides better function than most efforts at internal routing.

We've assembled our RM01 here as a race-ready package with a complete Shimano Ultegra Di2 group. The STI levers, derailleurs, brakes, and crankset are all there. The rest of the build kit is comprised of parts we'd ride on our race bikes. You'll get an Easton EC90 SLX3 Handlebar and EA70 Stem, and the BMC RM01 Racepost TCC Seatpost with a Fizik Antrares 2 perched on top. The Mavic Ksyrium Elite wheels shod in Continental Ultra Race tires are ready for anything.

The BMC Race Machine RM01/Shimano Ultegra Di2 Complete Bike is available in White. It comes in six sizes from 47 - 60cm. The Race Machine passes the strictest CEN testing for frame fatigue. It has no weight limit and comes with a three year manufacturer's warranty.
