With the unveiling of the third generation Teammachine SLR01, BMC join the growing list of manufacturers to offer a premium race bike with rim and disc brake options. BMC’s most important model has defined the company’s progress – the first generation in 2011 was BMC’s first carbon monocoque, and helped Cadel Evans to his 2011 Tour win, and Philippe Gilbert to his 2012 world championship title. Generation two in 2013 was first to employ ACE (Accelerated Composite Evolution) Technology, and carried Greg Van Avermaet to the 2016 Olympic title and some great one-day results in 2017 so far.
Even though the existing SLR01 is hardly being outgunned on the road, BMC’s head of R & D, Stefan Christ explained that, “Improving the existing Teammachine was no mean feat, and people have asked us why even change a wining formula? The answer is simple – we knew we could create a new, more competitive one! Besides, if you don’t keep on innovating, you get left behind.”
BMC had three primary goals with the new bike: keep the bike’s balance of stiffness, weight and compliance; add integration; and add discs.
Development feedback and input came from BMC Racing Team professionals such as Van Avermaet and Richie Porte, and the now-retired Evans, who has an ongoing development and ambassadorial role with the company. Evans said that he’s raced and trained for around 150,000km on successive generations of the SLR01.
The third generation SLR01 project began with known design targets and loads (such as braking force), but also had to conform to UCI rules and existing frame geometry. Conventional methods start with a shape calculation – allowing room for moving parts and so on, then a laminate calculation to decide on carbon materials and layup, and finally comes protot
