Built around Giant’s AeroSystem Shaping, the Propel Advanced 1 focuses on real-world aerodynamic efficiency. Truncated ellipse tube profiles are designed to reduce drag across a wide range of yaw angles, helping you maintain speed whether riding solo, in a break or pushing into a headwind.
The Advanced-Grade Composite frame and fork balance stiffness and weight, delivering a responsive feel when accelerating while remaining stable at high speeds. Internal cable routing through the stem and head tube keeps airflow clean and makes it easier to adjust or swap cockpit components without fully re-cabling the bike.
Shimano 105 Di2 brings reliable electronic shifting with a wide 12-speed gear range, suited to fast flats and rolling terrain. Hydraulic disc brakes provide consistent control, even when braking hard from high speed.
Deep-section SLR 2 50 carbon wheels add aerodynamic advantage while remaining predictable in crosswinds, paired with fast-rolling Gavia Course 0 tubeless tyres for grip and efficiency. With its blend of aero gains, modern integration and everyday usability, the Propel Advanced 1 is built for riders who want to go fast and stay there.
