teammachine SLR02 altitude

Acceleration redefined

The requirements for the teammachine were defined by WorldTour racing. Riders like Philippe Gilbert, Cadel Evans and Tejay van Garderen asked for a bike that combines lightweight, for the long climbs, with the very best acceleration for aggressive attacks. We listened to their needs, and suggestions, and then dug deep into our bag of engineering tricks to bring the new SLR01's performance to a whole new level. With our new ACE technology, we accelerated the normal design and engineering process by running an incredible 34'000 computer-generated prototypes. The end result is the new teammachine SLR01 offering what we like to call, "acceleration redefined."

Concept

Lightweight: The SLR02 was designed for those looking for legendary BMC teammachine performance, but at a more affordable price point. To make the SLR02 more affordable, some design elements are changed from the SLR01, like the SLR01’s proprietary seatpost and the full carbon dropouts, but the frame design and stiffness values remain identical. With a scant frame weight of just 950 grams, the SLR02 still offers a very high stiffness to weight ratio. The lateral stiffness maximizes power transfer while its torsional stiffness boosts steering precision.

ACE development process: As far as it goes. For Charles Darwin, all life adheres to an evolutionary process. According to this principle, it took several thousand years for humans to morph from ape-like creatures into the advanced beings we are today. Similarly, by looking back one hundred or so years, anyone can see where bike design originated, and to where it has evolved: from simple lugged steel construction, to fantastically complicated monocoque carbon fiber creations. At BMC we decided to try and speed up the process, and replaced the “hand of God” with highly sophisticated computerized design optimization. First, we started by defining the performance criteria of a world-class road bike frame, and by stating such open parameters of frame design as tube cross-sections, tube placement, and carbon fiber lay-up. From there we established a calculation model capable of computing through finite element method (FEM) the bike frame’s real-world performance based on our established parameters. The last step of the process was to use an algorithm to run tens of thousands of reiterative design calculations to identify ideal frame characteristics. This process is neither cheap, nor extremely fast, but in the end we ran over 34 thousand design iterations over the course of one full year of engineering! As the first prototypes appeared, designed according to FEM results, we were surprised how closely we had come to achieving our goals. And our professional athletes were almost instantly convinced and satisfied. In the end, we needed fewer prototypes than usual to confirm the final product.

Comfortable: Believe it or not, Cadel Evan’s main requirement for a race bike is comfort. He needs to ride long hours every day without being sapped of his energy, and arrive as fresh as possible at the finish line. We solve this need with our Tuned Compliance Concept (TCC) by combining stiffness in laterally flexing directions, and compliance in vertical directions. Specifically, carbon-fiber lay-up and tube shapes are optimized so that the bike can resist rider-actuated forces, while at the same time giving in to road forces.

ACE

Accelerated Composites Evolution

For the first time in industry history, BMC replaced traditional design prototyping processes with powerful Accelerated Composites Evolution Technology (ACE). This sophisticated reiterative computer modeling program electronically prototyped more than 34,000 possible frame configurations with the goal of optimizing geometry, tube cross sections, carbon lay-up, ride quality, and handling characteristics. The first result of ACE is the new teammachine SLR01: it embodies a perfectly balanced combination of weight, stiffness, and vertical compliance.
