Unleash your sprint with 200 meters to go. Close a gap chase back launch a solo attack. This new aero road machine is made for the moments that count. More aero more adjustable more ways to win. The propel advanced sl frameset is engineered with giants aerosystem shaping technology which means every tube shape and angle is optimized for minimal drag. The tubes feature a truncated ellipse shape for a frame that is ultra stiff and superlight while the integrated seatpost reduces weight improves aero performance and adds road smoothing compliance. This special edition honors team jayco alula with the teams bold colors. 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 produces outstanding 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 sl grade composite frameset features giants pro level composite materials and manufacturing processes. The result is 225 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 giants 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. 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. 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.
