Now even faster, this aero rocketship is built for speed when it matters most. The re-engineered frameset is even more adept at slicing through wind, and it's also lighter than the previous generation. The result? Race-winning efficiency that's hard to beat. 

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 handlebar and frame 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 now lighter than the previous generation for an improved stiffness-to-weight ratio.
• Vector Seatpost: This full-composite, lightweight and highly aerodynamic seatpost is engineered specifically for performance road riding.
  
• Ridesense Ready: This frame comes prepared to accept the Giant RideSense sensor and accompanying hardware.
