The Giant Propel Advanced 1 is a high-performance aero road racing machine engineered for pure speed and efficiency. For 2026, it arrives in the sophisticated Meteorite Mist finish, highlighting the sleek, aggressive lines of its Advanced-grade composite frame. Using Giant’s AeroSystem Shaping technology, every tube shape is refined through CFD analysis and wind-tunnel testing to minimize drag and maximize performance across a wide range of yaw angles.
This model is centered around the Shimano 105 Di2 12-speed electronic groupset, bringing professional-grade shifting precision and speed to a race-ready platform. Combined with a deep-section carbon wheelset and a redesigned cockpit that hides cables from the wind while remaining user-friendly, the Propel Advanced 1 is built to dominate breakaways, sprints, and solo efforts.

Key Technologies
AeroSystem Shaping: Every tube profile—from the head tube to the rear stays—is designed with a truncated ellipse airfoil shape to significantly reduce drag compared to traditional round tubes.
Shimano 105 Di2: Provides lightning-fast, wireless electronic shifting that remains reliable under load, ensuring you never miss a gear during a critical sprint.
OverDrive Aero: The D-shaped steerer tube and matching spacers provide an extremely aerodynamic, yet surprisingly easy-to-service, internal cable routing system.
SLR 2 50 WheelSystem: The 50mm deep carbon rims offer the perfect balance between aerodynamic gain and stable handling in crosswinds, making the bike versatile for both flat and rolling terrain.
