Giant Revolt Advanced
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.

Climbers and riders who want a light Specialized that isn't a full aero race bike. Not an endurance bike.
A lightweight road bike without the Tarmac's aero brief. It climbs and floats; it does not try to be a Tarmac SL7 in a crosswind. The position is still race-adjacent, not Roubaix-tall.
Racers who want a climbing Orbea. Orca Aero is the wind-cheating sibling.
Orbea's lightweight race bike, OMX carbon on high kits, and a fit that is race-low without S5 drama. OMX vs OMR changes weight more than geometry.
Gravel racers. URS if you want the adventure BMC.
BMC gravel-race bike. Lower and faster than URS, built for events.
