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.
Sportive and rough-road riders who found R5/S5 too low.
Cervelo endurance road: taller, more tire room, all-day. It is not a slow bike — it is an R5 that sat up.
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.
