Engineered for pure speed. Refined for pro‑level precision
The 2026 Giant Propel Advanced SL 0 in Arctic Light is the ultimate expression of Giant’s aero performance philosophy. Built around the lightest and most aerodynamic Propel frame ever produced, and equipped with the latest Shimano Dura‑Ace Di2 groupset, this flagship model is designed for riders who demand absolute efficiency, responsiveness, and race‑winning speed.
Advanced SL‑grade carbon: the pinnacle of Giant’s engineering
The SL 0 uses Giant’s Advanced SL‑grade composite, crafted using continuous‑fibre layup and one‑piece moulding for unmatched stiffness‑to‑weight performance. The integrated seatmast reduces weight and improves aerodynamic flow, giving the bike its unmistakable pro‑tour silhouette. Every contour is sculpted for speed, delivering a frame that feels razor‑sharp under power and incredibly stable at high velocity.
AeroSystem Shaping for real‑world aerodynamic advantage
Using Giant’s AeroSystem Shaping Technology, the frame employs truncated‑ellipse tube profiles optimised for performance across varying wind angles. Whether you’re launching a sprint, attacking solo, or holding a high‑speed tempo, the Propel Advanced SL 0 maintains aerodynamic efficiency and stability in turbulent, real‑world conditions.
Shimano Dura‑Ace Di2: the gold standard in electronic shifting
This edition of the SL 0 is equipped with the latest Shimano Dura‑Ace Di2 groupset — the benchmark for professional‑level performance. With lightning‑fast electronic shifting, refined ergonomics, and unmatched drivetrain efficiency, Dura‑Ace delivers crisp, flawless gear changes under any load. Paired with Shimano’s powerful hydraulic disc brakes, the SL 0 offers confident, predictable stopping in all conditions.
Integrated cockpit for seamless aero efficiency
The Contact SLR Aero integrated cockpit keeps the front end clean, stiff, and aerodynamic. Fully internal cable routing enhances airflow and aesthetics, while the refined ergonomics support both aggressive race positions and long‑distance comfort.
CADEX Aero WheelSystem: built for maximum speed
The SL 0 rolls on the CADEX Aero WheelSystem, engineered for aerodynamic efficiency, lateral stiffness, and rapid acceleration. Paired with tubeless tyres, the wheels deliver reduced rolling resistance, improved puncture protection, and exceptional cornering grip — essential for high‑speed racing and technical descents.
Arctic Light: a colourway that radiates speed and clarity
The Arctic Light finish gives the SL 0 a crisp, luminous presence. With its cool metallic tones and shimmering highlights, it accentuates the sculpted aero lines of the frame and delivers a premium aesthetic that stands out on the start line.
