The Propel Advanced Pro 0 is Giant's top-end aero road bike, built for riders who want to go fast and stay fast across a full range of conditions.
The Di2 electronic groupset, integrated cockpit, and aero wheel system all work as a single unit rather than a collection of individually specced components, and that coherence shows in how the bike rides.
Stiffness and responsiveness
The updated frameset is lighter than the previous generation with more torsional and pedalling stiffness. In practical terms, that means when you put power down hard, the bike responds immediately. There's no lag, no flex, no energy lost between input and output. For riders who race or train at a high level, that directness is exactly what you want when an attack goes or a sprint opens up.
Comfort over distance
Aero bikes have a reputation for being punishing on longer rides, and that's a fair criticism of older designs. Giant has addressed it directly here. The Vector seatpost is more compliant than the previous generation, the fork absorbs road buzz, and the integrated cockpit takes care of vibration up front. Tyre clearance has been extended to 32mm, which opens up the option of running higher-volume rubber for a smoother, faster ride on imperfect road surfaces.
For UK roads, where smooth tarmac is never guaranteed, that extra clearance is worth having.
Aerodynamics as a system
The AeroSystem frame, integrated cockpit, and aero wheel system are designed together rather than assembled from separate parts. Drag is reduced at the front end by the cockpit integration, rolling resistance comes down through the tyre and wheel pairing, and the overall silhouette of the bike is cleaner than a conventionally built road bike at this level.
The result is a bike that holds higher speeds for the same power output, which matters most when you're pushing hard on flat roads or working to maintain pace on long climbs.
Shimano Di2 electronic shifting
At this spec level on the Giant Propel Advanced Pro 0 Di2, shifting is precise and consistent in any conditions. No cable stretch to account for, no adjustments needed mid-season, no missed shifts when your hands are tired. For road racing or hard sportive riding, that reliability removes one variable you'd otherwise have to manage.

Who this bike suits
The Giant Propel Advanced Pro 0 is a serious aero road bike for riders who race, ride fast club runs, or train with power and want their equipment to match their ambitions. The geometry and build are oriented towards performance rather than all-day endurance comfort, though the updated compliance features make it significantly more liveable than previous generations.
