Hang with the fast group go for the sprint cheat the wind on a solo ride. The new Propel Advanced Pro is now lighter smoother and more efficient delivering higher speeds to help you maximize every effort. Key Performance Factors Instant Speed In the moments when explosive speed matters most—launching an attack chasing a break or sprinting for the finish line—the new Propel Advanced Pro is quicker and more dynamic than ever. The frameset is lighter than the previous generation with greater torsional stiffness and pedaling stiffness—so you feel instantaneous reaction when you make your move. Sustained Speed A reengineered frameset and integrated components combine for a smoother ride when you’re rolling in the group or piling up training miles. The Vector seatpost offers greater compliance compared to the previous generation while the fork and integrated cockpit absorb bumps and vibrations up front. And additional tire clearance allows for high-volume tires up to 32mm further smoothing out the ride to help you maintain higher speeds with less fatigue. Top-End Speed The frameset cockpit wheels and tires form a unified system that lowers total resistance when you’re pushing high speeds. The AeroSystem frame and integrated cockpit minimize drag while the aero WheelSystem and tires reduce rolling resistance. That means more speed for taking pulls rolling off the front or driving the pace across flats and over climbs. Advanced Composite Technology Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction. AeroSystem Shaping Technology Through CFD Computational Fluid Dynamics and wind-tunnel data engineers optimize each tube shape to deliver superior aerodynamic performance. 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. 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. Vector Seatpost This full-composite lightweight and highly aerodynamic seatpost is engineered specifically for performance road riding.
