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
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’s lighter than the previous generation for an even greater stiffness-to-weight ratio.
