Season:2027

Brand:Giant

Code:9074027

Aero performance made more accessible

The Giant Propel Advanced Pro 1 in Cryo Silver brings the speed, stiffness, and aerodynamic efficiency of the Propel platform to a wider range of riders. With its Advanced‑grade carbon frame, integrated cockpit, and the latest Shimano 105 Di2 electronic drivetrain, this model delivers race‑ready performance at an exceptional value.

Advanced‑grade carbon for responsive, efficient speed

The Propel Advanced Pro 1 uses Giant’s Advanced‑grade composite, engineered for impressive stiffness‑to‑weight performance and real‑world aerodynamic gains. Every tube is shaped using AeroSystem Shaping Technology, producing truncated‑ellipse profiles optimised for airflow across varying wind angles. The result is a bike that accelerates quickly, holds speed effortlessly, and remains stable in crosswinds — ideal for fast group rides, crits, and weekend races.

Integrated aero cockpit for clean, efficient airflow

The Contact Aero integrated handlebar and stem create a sleek, drag‑reducing front end with fully internal cable routing. This not only improves aerodynamic efficiency but also gives the bike a modern, minimalist aesthetic. The geometry blends aggressive race positioning with long‑ride comfort, making the Advanced Pro 1 versatile enough for everything from crit racing to endurance events.

Shimano 105 Di2: modern electronic shifting, exceptional value

Equipped with the latest Shimano 105 Di2 12‑speed groupset, the Propel Advanced Pro 1 delivers smooth, precise electronic shifting with the reliability and ergonomics riders expect from Shimano’s Di2 platform. Paired with powerful hydraulic disc brakes, the drivetrain offers consistent performance in all conditions — ideal for riders stepping into electronic shifting for the first time.

SLR Aero WheelSystem for speed and stability

The bike rolls on Giant’s SLR Aero WheelSystem, engineered for aerodynamic efficiency, lateral stiffness, and responsive handling. Tubeless‑ready rims paired with high‑performance tyres reduce rolling resistance, improve puncture protection, and enhance cornering grip — essential for high‑speed racing and technical descents.

Cryo Silver: crisp, modern, and unmistakably fast

The Cryo Silver colourway gives the bike a clean, high‑tech aesthetic. Cool metallic tones highlight the sculpted aero lines of the frame, creating a finish that looks sharp, modern, and undeniably fast.

Professional Opinion
  • Aerosystem
    Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
  • Advanced Composite
    Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.
  • Vector Integrated Seatpost
    The integrated vector seatpost saves weight compared to standard composite posts, while improving aerodynamics and adding road-smoothing compliance.
  • Overdrive Aero
    Found inside the head tube of the Defy, Propel and TCR ranges, the D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easier to service system of internally routed brake and derailleur cables.
  • Tubeless System
    Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
