The Giant Propel Advanced SL 1 is a thoroughbred race bike built for elite performance. It’s designed to help riders close gaps, launch attacks and hold high speeds with maximum efficiency. Featuring Advanced SL-grade composite construction, this flagship frame sheds weight while boosting stiffness-to-weight ratio – saving 150g over the previous model without compromising strength.
At the heart of the Propel’s performance is AeroSystem Shaping Technology, developed using CFD analysis and dynamic wind tunnel testing. The result is a frameset optimised for aerodynamic efficiency across all yaw angles. The truncated ellipse tube profiles and integrated Contact SLR Aero cockpit work together to reduce drag and increase speed across varied conditions.
The fully internal cable routing through the head tube and stem delivers clean lines and easier adjustability. Whether you’re tweaking fit or upgrading components, it’s simple to fine-tune the cockpit to your ideal setup.
A full Shimano Ultegra Di2 R8170 2x12-speed drivetrain offers fast, accurate wireless shifting, while Ultegra hydraulic disc brakes ensure consistent stopping power with RT-CL800 rotors. For those serious about data, the bike also comes fitted with a Giant Power Pro dual-sided power meter, ideal for structured training and race pacing.
Rolling on the CADEX 50 Disc WheelSystem with carbon aero spokes and CADEX Aero tubeless tyres, the Propel SL 1 offers outstanding aerodynamics and responsive acceleration. The integrated seatpost design further enhances ride quality while maintaining a stiff, efficient rear triangle.
Whether you're sprinting for the line, pulling through the breakaway or chasing your next PR, the Giant Propel Advanced SL 1 delivers pro-level performance with no compromises.
