Highlights
AeroSystem Shaping
This is the exact aero platform the pros race, tuned through wind-tunnel testing and airflow analysis to stay fast at every wind angle. Start here and you are building on a proven race chassis.
Advanced SL-Grade Composite
Giant's flagship composite is 225 grams lighter than the last generation, so your finished build starts from a serious weight advantage. Every gram you save here is one you never have to fight uphill.
OverDrive Aero Steerer
The full-composite steerer delivers sharp, confident steering when you throw the bike into a corner. It is the front-end stiffness a race build deserves.
Integrated Seatpost
The built-in seatpost trims weight and cleans up the tail of the bike for better airflow. It rounds out a frameset made to be raced, not just admired.
Blank Canvas Build
As a frameset, this is your foundation for a fully custom Propel spec'd exactly how you ride. Steve and Brian can help you build it right the first time.
