Giant 2026 Propel Advanced 2 105 Road Bike

 

The Giant Propel can’t slow time, but when you drop your head and start pushing watts, something happens. Unleash your sprint with 200 meters to go. Close the gap or launch a solo attack. This pro-level road machine is made for the moments that count. More aero, more adjustable, more ways to win.

Exhaustive engineering, holistic design, and real-world testing. It all comes together with the Propel aero road bike. The result? Race wins. Lots of them.

 

Built to win

The Propel Advanced SL has carried top pros like Dylan Groenewegen and Michael Matthews of Team Jayco-AlUla to some of the biggest wins in their careers. With scores of victories—in sprints and in breakaways—it’s the choice for riders who are ready to attack. These riders played a key role in the development of the Propel Advanced SL, which is 225g lighter and 9.2 percent stiffer than the previous generation. Whenever speed matters most—against the wind, against the clock, against competitors—this is your advantage.

 

Key features of the Propel range

Integrated Aerodynamics

Truncated ellipse airfoil shapes are used in the down tube, seat tube and seat stays. Working with renowned aerodynamicists at the GST wind tunnel in Germany to accurately simulate real-world riding conditions, a dynamic mannequin was used to analyze the aerodynamic factors of not just the bike, but rider and bike together. This process most accurately replicates the effects of a rider pedaling against various wind speeds and angles. 
 

The frameset is part of the story, but not the whole story. The proprietary Contact SLR Aero handlebar and stem also reduce drag, as do the CADEX 50 wheels and CADEX Aero tires found on the flagship Propel Advanced SL. When comparing the complete new Propel Advanced SL bike to the previous generation, the new model improves aerodynamic drag by 6.21 watts. This equates to a savings of 27 seconds over 40km at 40kph.

 

Race-winning efficiency

Tests show that the latest Propel Advanced SL frameset is not only one of the lightest in the aero road category, but it also achieves significant gains in stiffness. Lighter weight plus increased stiffness equals better efficiency on the road. When determining the precise tubing shapes and diameters, along with the layup of the Advanced SL composite material that’s used to create the frame and fork, Giant engineers focused on two key areas of stiffness: frame stiffness, which determines the amount of overall frame and fork torsional flex under load; and pedaling stiffness, which measures the lateral flex of the bottom bracket area under load.

 

Easier adjustability

The cockpit is completely redesigned with an innovative new two-piece Contact SLR Aero handlebar and stem setup that makes it easier to change components and dial in a precise fit. This new OverDrive Aero system keeps the cables and hoses hidden from the wind while avoiding the complexities associated with fully integrated handlebar/stem designs that are common with many of today’s aero road bikes. The new Contact SLR Aero carbon handlebar has flattened tops for aero efficiency and hand comfort, along with a deeper drop for added control while sprinting, cornering and descending.

 

Propel Advanced

Maximize your watts during sprints, breakaways and solo attacks. This composite road machine offers proven aero performance and one of the lightest framesets in its category. Because small gains lead to big wins. It’s made with an Advanced-grade composite frame and fork along with a Vector seatpost for a smooth, race-tuned feel on the road.
