Racers and fit club riders who want a low stack without full aero integration. If the Aeroad cockpit feels like too much, this is the sibling.
Canyon's lightweight race bike: snappy, precise, and less of a wind-cheater than the Aeroad. It rewards a committed position and calm hands in corners rather than a slammed aero tuck.
Riders who race or ride fast on rolling and flat roads and are happy with a long, low fit. Not the pick if you want a tall stack.
A deep-section race bike that wants speed. The cockpit is integrated and the front end is stiff; it holds a line in crosswinds better than older Aeroads, but it still feels like an aero bike.
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.
Aero racers. Addict RC if you want light; Addict Gravel if you want dirt.
Scott's aero race bike — a benchmark for 'this is how you do aero' in recent reviews. Stiff, fast, still a race stack/reach chart.
