Racers and fit riders who want Giant's race geometry without Propel's deep tubes.
Giant's lightweight race bike: compact sloping top tube, sharp steering, and a fit that has been a stack/reach reference for a long time. Less aero drama than Propel.
Gravel racers. Caledonia if you want road endurance with some dirt; Aspero-5 if you want the aero gravel version.
Gravel-race Cervelo. Trail mixer, low and fast, built for events rather than touring. Aspero-5 adds aero.
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.

Reviews. Cervelo Aspero 5 review – "Haul ass, not cargo". Cervelo's Aspero 5 gravel racer is designed for maximum all surface speed but just how fast is it?
A look at the Cervelo Aspero Force eTap AXS 1 Disc. A very fast gravel bike with sleek looks but short on versatility.
Orbea has dropped many of the aero optimisations of the previous Orca, while it has unified the geometry across the OMX and OMR-tier frames.
Orbea says, “the Orca is around 3W faster than an aero bike, for an average rider, on a 5% slope, and around 6W faster on a 10% slope.” The Orca OMX has claimed ...
