Santa Cruz Stigmata
CX and gravel racers who already like Santa Cruz. Not a bikepacking mule.
Drop-bar Santa Cruz: CX/gravel race geometry, not a touring bike. It feels like the brand's MTB handling translated to drop bars.

Sprinters and fast road riders who picked aero over weight. If you wanted the climbing bike in this era, compare stack/reach against the Émonda instead.
Gen 7 Madone: a pure aero race bike built on Kammtail Virtual Foil tubes with the IsoFlow cutout for rear compliance. It is the fast, heavier half of Trek's race line — Émonda is still the light bike in these years.
Climbers and riders who want a light Specialized that isn't a full aero race bike. Not an endurance bike.
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.
