Giant Propel Advanced Pro 1 Di2 Road Bike 2027 in Cryo Silver

Season:2027

Brand:Giant

Code:90740271

Designed for riders who demand aerodynamic performance and cutting-edge technology, the Giant Propel Advanced Pro 1-Di2 delivers race-ready speed with impressive efficiency and control. Built around Giant’s Advanced-grade composite aero frameset, this high-performance road bike blends aerodynamic shaping, lightweight construction and responsive handling for explosive acceleration and sustained speed.

The Advanced composite frame and Advanced SL fork utilise Giant’s AeroSystem shaping to minimise drag while maximising pedalling stiffness. Whether launching attacks, bridging to a breakaway or maintaining speed in a fast group ride, the Propel Advanced Pro responds instantly to every pedal stroke.

Shimano’s 105 Di2 electronic drivetrain offers smooth, precise wireless shifting with exceptional reliability, while a power-meter equipped crankset helps riders monitor performance and training efforts. Giant SLR 1 50 carbon wheels paired with tubeless Giant Gavia tyres reduce rolling resistance and improve aerodynamic efficiency. With tyre clearance up to 32mm and a compliant Vector composite seatpost, this bike balances elite race performance with long-ride comfort.

Instant Speed

In the moments when explosive speed matters most—launching an attack, chasing a break, or sprinting for the finish line—the new Propel Advanced Pro is quicker and more dynamic than ever. The frameset is lighter than the previous generation with greater torsional stiffness and pedaling 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 are 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. 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 are pushing high speeds. The AeroSystem frame and integrated cockpit minimize drag, while the aero WheelSystem and tyres reduce rolling resistance. This means more speed for taking pulls, rolling off the front, or driving the pace across flats and over climbs.
