Propel Advanced
SL Disc 1
Built to give you an edge when it counts most—on the attack, in the sprint, going all out—this aero road bike delivers unbeatable efficiency and race performance.
Key Performance Factors
Integrated aerodynamics
AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimizes aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and Contact SLR Aero cockpit produce the best overall aero performance.
Total control
Integrated disc brakes deliver powerful stopping power and modulation for added control in all conditions and weather. Thru-axles boost stiffness and improve overall handling. And an integrated WheelSystem with a 65mm deep rear rim and 42mm front rim optimizes aerodynamics and control.
Unrivaled efficiency
Advanced SL-grade composite frameset features Giant’s highest performance materials and manufacturing processes for optimized stiffness and the lowest weight in its category.
Highlights
The Propel Advanced SL Disc is engineered with Giant’s AeroSystem Shaping technology, which means every tube shape and angle is optimized for minimal drag. The tubes feature a truncated ellipse shape for a frame that is ultra-stiff and superlight. Disc-brake technology is integrated into the frameset with flat-mount calipers and thru-axles for optimal wheel stiffness and braking performance.
Techs & Features
Advanced SL Composite Technology
Professional Grade raw carbon fiber is woven in our composite factory to produce our lightest, stiffest and highest quality frames. This is the technology used by Giant’s pro racers in almost every cycling discipline.
AeroSystem Shaping Technology
Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
OverDrive 2
The most advanced steerer tube technology in today’s Giant bikes. Designed to offer unprecedented front-end steering performance, the system’s oversized headset bearings (1 1/2” lower, 1 1/4” upper) and tapered steerer tube work in harmony to provide supreme steering stiffness.
Tubeless System
Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
RideSense Ready
This frame comes prepared to accept the Giant RideSense sensor and accompanying hardware.
Integrated Seatpost
Designed as a key performance factor in the overall frameset, the integrated seatpost saves up to 45 grams compared to standard composite posts, while improving aerodynamics and adding road-smoothing compliance.
