At the absolute pinnacle of aero road performance, the Giant Propel Advanced SL 0-Red is built for riders who demand the fastest, most efficient race machine possible. Designed for elite racing and uncompromising speed, this flagship aero bike maximises every watt to deliver exceptional acceleration, efficiency and aerodynamic advantage.
The Advanced SL composite frameset is Giant’s lightest and stiffest aero platform, engineered using AeroSystem shaping to minimise drag while maximising pedalling efficiency. An integrated seatpost and cockpit further improve aerodynamics while delivering improved compliance for smoother riding over long race distances.
SRAM’s flagship RED AXS wireless electronic drivetrain provides ultra-precise shifting and race-ready performance, paired with a power-meter-equipped crankset to monitor and optimise your efforts. The CADEX Max 50 carbon wheel system with CADEX Aero tubeless tyres reduces rolling resistance and aerodynamic drag for maximum speed across flats, climbs and descents.
Built to dominate breakaways, lead the sprint and hold top speed for longer, the Propel Advanced SL 0-Red represents the ultimate expression of aero road performance.
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 SL is quicker and more dynamic than ever. The whole system sheds 355g from the previous generation and is also more efficient with 14.2% more torsional stiffness and 14.8% greater pedalling stiffness—so you feel instantaneous reaction when you make your move. From breakaways to the final sprint. On flat roads, climbs or descents. The reengineered Propel Advanced SL cuts through wind and maximises watts, optimising your energy through every dimension of speed: top-end speed, instant speed and sustained speed.
Sustained Speed
Engineered for full-bike compliance, the new Propel Advanced SL delivers a significantly smoother ride when you’re rolling in the group or piling up training miles. The Vector integrated seatpost has 25% greater compliance compared to the previous generation. The fork and integrated cockpit absorb bumps and vibrations up front with 15% added compliance. 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 in the wind—whether you’re on a solo break, taking pulls at the front, or powering away on a climb. The AeroSystem frame and integrated cockpit minimise drag, while the new CADEX Max 50 WheelSystem and Aero tyres reduce rolling resistance. It all adds up to an 18.4W aero and rolling resistance advantages.
