Our verdict
Overall
out of 100, average of 6 categories
A pro-team time trial bike for UCI racers who want a ready-to-race complete bike with Di2 and deep carbon wheels in one box. There is no built-in hydration or storage, and the integrated cockpit with a single seat angle makes fit less forgiving, so triathletes will be adding accessories and checking sizing carefully.
