2026 PROPEL ADVANCED 2 Road Bike
The 2026 Giant Propel Advanced 2 redefines speed with a perfect blend of aerodynamics, stiffness, and lightweight design. Built from Advanced-Grade Composite, this new-generation aero road bike cuts through the wind with proven tunnel-tested performance while offering enhanced efficiency and handling.
Unlike overly complex internal setups, the new hidden cable routing keeps the cockpit clean and aerodynamic while remaining simple to adjust and service—making it both race-ready and rider-friendly.
Equipped with a full Shimano 105 12-speed groupset, precise electronic shifting, and hydraulic disc brakes, the Propel Advanced 2 offers smooth gear transitions and powerful stopping power in all conditions. Paired with Giant’s P-A1 Disc alloy wheel system and Gavia Course 0 tubeless tires, this bike delivers confident handling, comfort, and speed on every ride.
