What bike was Sagan riding in Gent Wevelgem?

It's not a supersix evo. Looks a bit like a CAAD10 in some respects (e.g. junction of downtube and headtube), but the top tube slopes more, the seatstays are different and the rear brake is internally routed. Also note the profiled seat tube in front of the rear wheel.. Is it a custom alu job just for him?
