The Propel Advanced SL 1 2025 Aero Race Bike is engineered for pure speed, combining cutting-edge aerodynamics with an ultra-light carbon frame. Designed for competitive riders who demand top-tier performance, this bike delivers explosive acceleration, razor-sharp handling, and unmatched efficiency on the road. Every detail is optimized to minimize drag, ensuring maximum speed whether sprinting, attacking climbs, or breaking away from the pack.

The advanced-grade carbon frame is built using the latest aerodynamic technology, reducing air resistance without compromising stiffness. This means more power is transferred directly to the pedals, giving riders an edge in every race. The integrated cockpit and internal cable routing create a sleek, streamlined look while enhancing overall aerodynamics.

Precision is key in racing, and this bike is equipped with an advanced electronic shifting system for lightning-fast, reliable gear changes. Whether climbing steep gradients or powering through flat sections, every shift is smooth and effortless, keeping riders in complete control. The carbon wheels are designed for speed and stability, cutting through the wind while maintaining excellent traction and responsiveness.

Equipped with an electronic groupset, this bike offers seamless, precise shifting at the touch of a button. Instant gear changes allow riders to adapt to terrain changes without losing momentum, ensuring smooth transitions between climbs, flats, and descents. The high-performance carbon wheels further enhance speed and stability, delivering reduced rolling resistance and improved handling in crosswinds.

Braking performance is just as critical as acceleration, and this bike is equipped with hydraulic disc brakes that provide unmatched stopping power and control. Whether descending steep switchbacks or navigating tight corners in a high-speed peloton, these brakes offer consistent performance in all conditions. The premium tires deliver outstanding grip and durability, ensuring riders stay connected to the road no matter the conditions.

For those who refuse to compromise on speed and performance, the Propel Advanced SL 1 2025 Aero Race Bike is the ultimate machine. Whether competing in elite races, setting personal bests, or leading the pack on fast-paced group rides, this bike delivers an aerodynamic advantage that makes every watt count. With cutting-edge engineering and race-proven technology, it’s built for cyclists who demand nothing but the best.

Specifications

Unleash your sprint with 200 meters to go. Close a gap, chase back, launch a solo attack. This pro-level road machine is made for the moments that count. More aero, more adjustable, more ways to win.

Key Performance Factors

Integrated aerodynamics

AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimizes aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and Contact SLR Aero cockpit produce the best overall aero performance.

Easier adjustability

Cable routing through the stem and head tube makes it quicker and easier to adjust or change cockpit components and fine-tune performance and riding position.

Race-winning efficiency

Advanced SL-grade composite frameset features Giant’s pro-level composite materials and manufacturing processes. The result is 150 grams of weight savings compared to the previous generation and an even greater stiffness-to-weight advantage.
