PROPEL ADVANCED SL 1

Pro-Level Aero Race Bike for All-Out Speed

Propel Advanced SL 1 is built for the decisive moments of racing: the final 200 meters, the solo attack, the closing of a critical gap. Its Advanced SL-grade composite frameset, optimized AeroSystem Shaping, and fully integrated cockpit deliver class-leading aerodynamics, precise adjustability, and race-winning stiffness-to-weight. Lighter, faster, and more efficient, it turns every watt into maximum speed.

DISCOVER

INTEGRATED AERODYNAMICS

AeroSystem Shaping, developed through CFD analysis and dynamic wind-tunnel testing, optimizes tube profiles at every yaw angle. Truncated ellipse airfoil tube shapes and the Contact SLR Aero cockpit work together as a single aero system, delivering best-in-class aerodynamic performance in real-world racing conditions.

EASIER ADJUSTABILITY

Internal cable routing through the stem and head tube simplifies cockpit tuning and maintenance. Bar and stem changes, position refinements, and fit adjustments are quicker and cleaner, allowing riders to fine‑tune performance and riding posture without compromising the fully integrated aero design.

RACE-WINNING EFFICIENCY

The Advanced SL-grade composite frameset uses Giant’s pro-level carbon materials and layup techniques, saving approximately 150 grams over the previous generation while further improving stiffness-to-weight. The result is explosive responsiveness under power, efficient climbing, and a bike that rewards every effort with more speed.
