Key Performance FactorsIntegrated aerodynamicsAeroSystem 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 adjustabilityAll-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 efficiencyAdvanced-grade composite frameset features high-performance materials and proprietary manufacturing processes. As a result, its lighter than the previous generation for an even greater stiffness-to-weight ratio.
