Giant Propel Advanced Pro Dure Ace Road Bike

This aero rocketship is built for speed when it matters most, engineered to slice through wind.This product is lighter than the previous generation and engineered to slice through wind. The result is race-winning efficiency that puts you ahead of the pack.Features: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/SL Aero cockpit produce the best overall aero performance.Easier adjustability: All-new 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-grade composite frameset features high-performance materials and proprietary manufacturing processes. As a result, it is lighter than the previous generation for an even greater stiffness-to-weight ratio.
