Data compiled from Computational Fluid Dynamics research and wind-tunnel tests was used to optimize the shape of every frameset tube and junction for overall system aerodynamics.
Propel Advanced 2
Aerosystem Shaping Technology
Giant’s original oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
Optimized for Giant’s chainstay integrated, wireless data transmitter. The fully integrated, removable transmitter sends wheelspeed and cadence information directly to any ANT+ compatible computer.
This full composite, lightweight and highly aerodynamic seatpost is engineered specifically for the unyielding demands of performance road riders.
Advanced Composite Frame
High Performance Grade raw carbon fiber and Giant’s proprietary resin formula is used to produce custom composite material in our own composite factory that is extremely lightweight, stiff and compliant.
