Giant Propel Advanced Pro 1 Road Bike

This aero rocketship is built for speed when it matters most, being lighter than the previous generation and engineered to slice through wind.This results in 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.
