Aero excellence meets pro‑level precision.
The 2027 Giant Propel Advanced SL 0 in
Prism Pearl is the ultimate expression of Giant’s aero engineering — a flagship race machine built for riders who demand uncompromising speed, stiffness, and integration. With its shimmering multi‑layer Prism Pearl finish and the latest Shimano Dura‑Ace Di2 groupset, this is a bike designed to dominate sprints, breakaways, and high‑speed race days.
Advanced SL‑grade carbon: the lightest, fastest Propel frame ever
The SL 0 is built around Giant’s Advanced SL‑grade composite frame, crafted using continuous‑fibre layup and one‑piece moulding for exceptional stiffness‑to‑weight performance. The integrated seatmast reduces weight and improves aerodynamic flow, giving the bike its signature race‑ready 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 gains
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 off the front, or holding a fast 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 control and 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 ergonomic shaping provides comfort during long rides and stability during all‑out efforts.
CADEX Aero WheelSystem: engineered for pure speed
The SL 0 rolls on the CADEX Aero WheelSystem, designed to maximise aerodynamic efficiency, lateral stiffness, and 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.
Prism Pearl: a colourway that shifts with speed
The Prism Pearl finish gives the SL 0 a dynamic, iridescent character. Under sunlight, the frame shifts through subtle tones and highlights its sculpted aero lines — a premium finish for riders who want a bike that looks as fast as it rides.
