A lightweight road bike without the Tarmac's aero brief. It climbs and floats; it does not try to be a Tarmac SL7 in a crosswind. The position is still race-adjacent, not Roubaix-tall.
Climbers and riders who want a light Specialized that isn't a full aero race bike. Not an endurance bike. The S-Works kit is the halo build — same geometry as the non-S-Works page for this year, different parts.
