Pure aero performance. Zero compromises.
The 2027 Giant Propel Advanced SL 0 is the pinnacle of Giant’s aero engineering — a no‑compromise race machine built for riders who demand maximum speed, stiffness, and integration. Finished in the striking Superspeed Blue colourway, the SL 0 represents the fastest, lightest, and most refined Propel platform ever produced.
Advanced SL‑grade carbon: the lightest Propel frame yet
At the heart of the SL 0 is Giant’s Advanced SL‑grade composite frame, engineered using continuous‑fibre layup techniques and a one‑piece moulded construction. This results in exceptional stiffness‑to‑weight performance, razor‑sharp handling, and a frame that slices through the air with minimal drag. The integrated seatmast further reduces weight and improves aerodynamic flow, giving the SL 0 its unmistakable race‑ready silhouette.
AeroSystem Shaping for real‑world speed
Every tube profile is optimised using Giant’s AeroSystem Shaping Technology, producing truncated‑ellipse shapes that deliver aerodynamic gains across a wide range of yaw angles. Whether sprinting, attacking, or holding high‑speed tempo, the Propel Advanced SL 0 maintains stability and efficiency in turbulent, real‑world wind conditions.
SRAM Red AXS: wireless precision at its finest
The 2027 SL 0 comes equipped with the latest SRAM Red AXS groupset — lighter, faster, and more efficient than ever. With fully wireless shifting, refined ergonomics, and a wide‑range cassette, the drivetrain delivers crisp, instantaneous gear changes under load. Paired with SRAM’s powerful hydraulic disc brakes, the SL 0 offers confident stopping performance in all conditions.
Integrated cockpit for seamless control
The Contact SLR Aero cockpit is fully integrated, reducing drag while offering a clean, minimalist aesthetic. Internal cable routing keeps the front end sleek and silent, while the refined ergonomics provide comfort during long days in the saddle and stability during all‑out efforts.
Race‑ready wheels and tyres
The SL 0 rolls on Giant’s CADEX Aero WheelSystem, engineered for maximum aerodynamic efficiency and lateral stiffness. Paired with tubeless tyres, the setup delivers reduced rolling resistance, improved puncture protection, and enhanced cornering grip — essential for high‑speed racing and technical descents.
Superspeed Blue: a colourway built for the podium
The Superspeed Blue finish gives the SL 0 a bold, modern identity. With deep metallic tones and a gloss finish that highlights the frame’s sculpted aero lines, it’s a bike that looks as fast as it rides.
