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.
