Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
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.

Vector 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.
3
Advanced SL Composite
Professional-grade raw carbon material is woven in our own composite factory using our most advanced engineering and construction methods including: Continuous Fiber Technology to add strength while reducing weight; Carbon Nanotube Technology resin to improve impact resistance; and Fusion Process for lighter, stronger frame junctions.
4
OverDrive 2
Giant’s most advanced steerer tube technology offers unprecedented steering precision. Oversized headset bearings (1 1/2” lower, 1 1/4” upper) and a tapered steerer tube produce superior front-end stiffness.
5
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86mm wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
6
Internal Cable Routing
Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and performance.
7
Disc-Brake Integration
The frame and fork are engineered specifically for flat-mount disc-brakes, including front and rear 12mm thru-axles for reliable braking performance in all weather and road conditions.
8
AERO HANDLEBAR/STEM
Aero handlebar and stem are designed to reduce overall drag while minimizing weight.
9
AERO WHEELSYSTEM
Engineered with proprietary Dynamic Balanced Lacing technology, this aero WheelSystem delivers superior efficiency, pinpoint control and supreme aerodynamics.
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 40 grams compared to standard composite posts, while improving aerodynamics and adding road-smoothing compliance.
