Gravel racers coming from a road-race fit who found Checkpoint too tall or too touring-oriented.

Climbers and racers who want Scott without Foil's deep aero.
Scott's lightweight race bike: slim, syncros-integrated on high kits, and a fit that is race-low. Foil is the aero sibling.
Fast road riders who want aero on Giant's chart. TCR is the lighter, more conventional sibling.
Giant's aero race bike. Stiffer at the front, more wind-cheating than TCR, still in the same size-letter family so many riders can twin the two.
