2027 Giant Propel Advanced 1 - Carbon
Get the most from your hard-earned pedaling power. Whether it’s squeezing out more speed on solo rides or taking bragging rights in the group, the new lighter, smoother Propel Advanced makes the thrill of road speed accessible to all.
Key Performance Factors
Instant Speed
In the moments when explosive speed matters most, the new Propel Advanced is quicker and more dynamic than ever. The frameset is lighter than the previous generation with greater torsional stiffness and pedalling stiffness—so you feel instantaneous reaction when you make your move.
Sustained Speed
A reengineered frameset and integrated components combine for a smoother ride when you’re rolling in the group or piling up training miles. The Vector seatpost offers greater compliance compared to the previous generation, while the fork and integrated cockpit absorb bumps and vibrations up front. And additional tyre clearance allows for high-volume tyres up to 32mm, further smoothing out the ride to help you maintain higher speeds with less fatigue.
Top-End Speed
The frameset, cockpit, wheels and tyres form a unified system that lowers total resistance when you’re pushing high speeds. The AeroSystem frame and integrated cockpit minimise drag, while the aero WheelSystem and tyres reduce rolling resistance. That means more speed for taking pulls, rolling off the front, or driving the pace across flats and over climbs.
