Aero performance made more accessible than ever

The 2027 Giant Propel Advanced 2 in White brings the unmistakable speed and aerodynamic efficiency of the Propel platform to riders who want race‑inspired performance at an exceptional value. With its Advanced‑grade carbon frame, aero cockpit, and reliable Shimano 105 drivetrain, this model delivers fast acceleration, confident handling, and real aero gains — perfect for riders stepping into performance road cycling or upgrading from an aluminium race bike.

Advanced‑grade carbon for efficient, responsive speed

The Propel Advanced 2 uses Giant’s Advanced‑grade composite, engineered for excellent stiffness‑to‑weight performance and real‑world aerodynamic efficiency. 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 with ease, and remains stable in crosswinds.

Aero cockpit for clean, efficient airflow

The Contact SL Aero 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 2 versatile enough for everything from fast group rides to endurance events.

Shimano 105: reliable, smooth, and performance‑focused

Equipped with the latest Shimano 105 12‑speed mechanical drivetrain, the Propel Advanced 2 delivers crisp, dependable shifting with the ergonomics and performance riders expect from Shimano’s race‑inspired groupsets. Paired with powerful hydraulic disc brakes, the drivetrain offers consistent performance in all conditions — ideal for riders who want simplicity, durability, and value.

Aero WheelSystem for speed and stability

The bike rolls on Giant’s aerodynamic wheel system, designed for efficient airflow, lateral stiffness, and confident handling. Tubeless‑ready rims paired with high‑performance tyres reduce rolling resistance, improve puncture protection, and enhance cornering grip — essential for high‑speed riding and technical descents.

White: clean, modern, and unmistakably fast

The White colourway gives the bike a crisp, high‑contrast aesthetic. Bright, clean tones highlight the sculpted aero lines of the frame, creating a finish that looks sharp, modern, and built for speed.

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 Seatpost
    This full-composite, lightweight and highly aerodynamic seatpost is engineered specifically for performance road riding.
  • 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.
