If speed is your obsession, this is your bike. You train, you put in the work, and this aero machine does the rest. Built to give you an edge when it really counts - on the attack, in the sprint, going all out - it delivers energy-saving efficiency and race-winning aero performance.Developed and proven by the fastest sprinters on the CCC Team WorldTour squad, the Propel Advanced SL Disc delivers ultimate speed through integrated aerodynamics. It’s engineered with Giant’s AeroSystem Shaping technology, which means every tube shape and angle is optimised for minimal drag. These tubes feature a “truncated ellipse” shape, which also result in 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. For pro-level road performance and the ultimate aero advantage, the new Propel Advanced SL Disc puts you way ahead of the pack.

Integrated aerodynamics

AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimises 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 variable weather. Thru-axles boost stiffness and improve overall handling and an integrated WheelSystem with a 65mm rear rim and 42mm front rim optimizes aerodynamics and control.

Unrivalled efficiency

Advanced SL-grade carbon composite frameset features Giant’s highest performance materials and manufacturing processes for optimised stiffness and the lowest weight in its category.

Technologies

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.

RideSense

Giant’s chainstay integrated, wireless data transmitter. The removable transmitter sends wheel speed and cadence information directly to any ANT+ compatible computer.

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.

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.

PowerCore

A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design (92-millimeter wide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
