The Giant Propel Advanced 2 in Supernova is proof that you don't need a professional racing budget to slice through the air with authority. Built around the same "AeroSystem Shaping" philosophy as the flagship models, this bike utilizes high-performance Advanced-grade composite to minimize drag and maximize speed on the flats and in the sprints. The Supernova finish is an absolute head-turner—a deep, high-gloss red that looks like it’s glowing from within, giving the bike a fiery, aggressive presence that matches its racing intentions.
This model serves as the perfect entry point for riders looking to move into dedicated aero territory without the complexity of electronic shifting. It features the latest Shimano 105 12-speed mechanical groupset, offering the same wide gear range and crisp shifting as its electronic siblings but with traditional mechanical reliability. The integrated OverDrive Aero system keeps the cockpit remarkably clean by routing cables through the stem and into the frame, ensuring that the only thing catching the wind is the rider. With its stiff, responsive frame and stable handling, the Propel Advanced 2 is built to turn every ounce of effort into pure forward velocity.

Key Technologies
AeroSystem Shaping: Every tube profile is designed using CFD and wind tunnel data to provide the best aerodynamic performance at various wind angles.
Advanced Composite: High-performance grade raw carbon material is woven in Giant’s own factory to create a frame that is both exceptionally light and laterally stiff.
OverDrive Aero: A D-shaped fork steerer and matching stem spacers allow for a streamlined, integrated cable setup that is significantly easier to adjust than fully internal systems.
Compact Road Design: Creates a smaller, lighter, and stiffer frame while improving fit for a wider range of riders.
