Ridley Helium SLX
Racers who want Ridley without Noah's aero. Fenix if you need endurance stack.
Ridley's lightweight race bike. Belgian race fit, the climbing Ridley versus Noah aero. A long-running nameplate — compare years.

Gravel racers who want Cervelo's fastest dirt bike.
The aero Áspero. Same gravel-race brief with more wind-cheating. Still not a bikepacking frame.
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. Synapse is the taller sibling; SuperX is the CX/gravel race cousin.
The third-generation EVO: dropped seatstays and truncated-airfoil tubes turned Cannondale's climbing bike into an aero all-rounder with room for 30 mm tires. Lively rather than deep-aero.
