Giant Propel Advanced 0 ML Carbon. Tubless Tyres (tubes also possible). Meticulously developed for best-in-class aero road performance, this razor-sharp road racer offers a true advantage for sprinting and solo riding. The frame is handcrafted using Advanced-grade composite material to produce a bike that’s lightweight and stiff, with a sharp, responsive ride quality. Its disc brakes are completely integrated within the frame using flat-mount calipers and thru-axles designed to optimize the technology. From sprints to solo attacks, cornering and descents, the new Propel Advanced Pro Disc helps you slice through the wind and gain an advantage on the competition. 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/SL Aero cockpit help produce the best overall aero performance. Integrated disc brakes deliver powerful stopping power and modulation for added control in variable weather. Advanced-grade carbon frameset features high-performance materials and Giant manufacturing processes for optimized stiffness and the lowest weight in its category.
