Unleash your sprint with 200 meters to go. Close a gap chase back launch a solo attack. This pro-level road machine is made for the moments that count. More aero more adjustable more ways to win. 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 Aero cockpit produce the best overall aero performance. Easier adjustability 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 SL-grade composite frameset features Giant’s pro-level composite materials and manufacturing processes. The result is 150 grams of weight savings compared to the previous generation and an even greater stiffness-to-weight advantage. Advanced SL Composite Technology Professional Grade raw carbon fiber is woven in our composite factory to produce our lightest stiffest and highest quality frames. This is the technology used by Giant’s pro racers in almost every cycling discipline. AeroSystem Shaping Technology Through CFD Computational Fluid Dynamics and wind-tunnel data engineers optimize each tube shape to deliver superior aerodynamic performance. OverDrive Aero Found inside the head tube of the Defy Propel and TCR ranges the D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic easier to service system of internally routed brake and derailleur cables. Tubeless System Fewer flat tires. Greater traction. Less rolling resistance and a smoother faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits. Integrated Seatpost Designed as a key performance factor in the overall frameset the integrated seatpost saves up to 40 grams compared to standard composite posts while improving aerodynamics and adding road-smoothing compliance.
