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.
Racers who like Cannondale's handling and want the serviceable frame. Synapse is the taller sibling; SuperX is the CX/gravel race cousin.
The fourth-generation EVO keeps the third generation's geometry but goes lighter, slipperier, and back to a threaded BSA bottom bracket. Same fit as the 2020–2022 bike, easier to live with.
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.

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 ...
