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.
Racers who want BMC's classic race fit. Roadmachine if you need stack.
BMC's lightweight race bike: steep, precise, and a WorldTour stack/reach reference. Less aero than Teammachine R / Timemachine.
Riders who want a drop-bar bike for mixed-surface events, not a touring mule.
Gravel-race geometry with a distinctive front end. Quick to turn and happier on fast dirt than on loaded bikepacking tracks.
