BMC's lightweight race bike: steep, precise, and a WorldTour stack/reach reference. Less aero than Teammachine R / Timemachine.
Racers and fast club riders who want the modern Tarmac. If you came off an SL7, check that the stack/reach still matches your size.
The current Specialized race bike: lighter than SL7, still aero, and famously 'it just disappears' if the fit is right. Size by stack/reach — the 54/56 split is where a lot of riders hop.
