25 GIANT PROPEL ADVANCED PRO 1 MEDIUM FROST SILVER

This aero rocketship is built for speed when it matters most. It’s lighter than the previous generation and engineered to slice through wind. The result? Race-winning efficiency that puts you ahead of the pack.
Key Performance Factors
Easier adjustability
AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimises aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and 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’s lighter than the previous generation for an even greater stiffness-to-weight ratio.

Weight
The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
