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.
Gravel riders who want Giant's drop-bar all-road, not a TCR with knobbies.
Giant's gravel bike: stable, mounts, and a position between Defy and a race gravel whip. The X variants add more suspension/travel attitude.
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.
Gravel racers who want Cervelo's fastest dirt bike.
The aero Áspero. Same gravel-race brief with more wind-cheating. Still not a bikepacking frame.
