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.
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.
Racers who like Cannondale's handling. Synapse is the taller sibling; SuperX is the CX/gravel race cousin.
The third-generation EVO: dropped seatstays and truncated-airfoil tubes turned Cannondale's climbing bike into an aero all-rounder with room for 30 mm tires. Lively rather than deep-aero.
