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.
Climbers and riders who bought Trek for weight before the Madone absorbed this brief. Compare stack/reach to the Madone SLR on current years.
The lightweight Trek race bike of the 2010s–early 2020s: rounder tubes than the Madone, a sharp climb, and less aero drama. Later years sit close to Madone numbers.
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.
Racers who want the Ineos/Dogma brief. F7 is the more attainable geometry cousin; Dogma X if you want endurance.
The halo Pinarello race bike: asymmetric stays, Italian race fit, and a size run in millimetres (430–595) that does not map 1:1 to S/M/L. It steers like a race bike that wants a skilled rider.
