Propel Advanced Pro 0-Di2 2025 - Ocean Twilight

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.
