BMC Teammachine SLR03 105
The requirements for the Teammachine family were defined by the demands of WorldTour racing – a delicate balance of ultra-lightweight for those grueling, above-category climbs, and rapid-fire acceleration for laying down aggressive attacks. In response, our engineers outdid themselves and developed our proprietary ACE Technology. With this, they accelerated the design and engineering process and developed 34,000 virtual prototypes in just one year. The end result is the Teammachine SLR – offering the world‘s finest balance of lightweight, stiffness and compliance.
If you want a 100% optimized bike frame, youll have to wait a very, very long time. At least this was the case before we developed ACE - the in-house computer software used daily by BMCs engineers to digitally simulate each stage and iteration of a new carbon frame. With ACE, we develop virtual prototypes before cutting actual molds, compressing years of testing and prototyping into mere months at the Impec R&D Lab in Grenchen, Switzerland.
ACE Accelerated Composites Evolution Technology
In 2011 we set out to advance our first-generation teammachine design. We soon realized that relying on human trial and error alone to improve a race bike of this caliber simply wasnt going to cut it. Collaborating with experts in the field, we developed ACE, or Accelerated Composites Evolution Technology. Replacing traditional prototyping processes, the iterative, computer-modelling program produced more than 34,000 possible frame configurations in just one year. This information enables us to virtually optimize geometrical structure, cross-sections and carbon fiber lay-ups to ensure that any physical prototypes produced are as close to the finished product as possible, thus reducing development time by light years.
With ACE technology, the most relevant performance characteristics of a race bike; weight, stiffness, and compliance, are combined in the best way possible to produce a unique ride and the ultimate in performance. Rather than physically prototyping every iterative stage during the engineering process, it allows us to speed up the evolutionary design process. Driven by more than 200 parameters such as cross-section dimensions, clearances, performance targets, our Finite Element Method (FEM) established a calculation model to determine the absolute real-world performance of the frame. Through complex computations, the characteristics of each iteration of frame design are realized and refined until the optimal combination of all parameters is found.
