Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
Propel Advanced SL
ULTIMATE SPEED
Unleash your sprint with 200 meters to go. Close a gap, chase back, launch a solo attack. This new aero road machine is made for the moments that count. More aero, more adjustable, more ways to win.
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 outstanding overall aero performance.
Easier adjustability
All-new cable routing through the handlebar and frame makes it quicker and easier to adjust or change cockpit components and fine-tune performance and riding position.
Race-winning efficiency
Advanced SL-grade composite frameset features Giant’s pro-level composite materials and manufacturing processes. The result is 225 grams of weight savings compared to the previous generation and an even greater stiffness-to-weight advantage.
Highlights of the Propel Advanced SL
This all-new aero road machine is designed and engineered for one main purpose: speed. With its AeroSystem Shaping technology and race-winning efficiency, it’s the bike of choice for the WorldTour sprinters on Team BikeExchange-Jayco and the world’s fastest triathletes. The tubes feature a truncated ellipse shape for a frame that is both ultra-stiff and superlight. Now 225 grams lighter than the previous generation, it offers a competitive edge when it matters most.

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, CNT Technology and Fusion Process.
3
Aero Tubeless WheelSystem
Engineered with proprietary Dynamic Balanced Lacing technology, this aero WheelSystem and tubeless tires deliver superior efficiency, pinpoint control and supreme aerodynamics.
4
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.
5
OverDrive Aero
Found inside the head tube of the all-new Propel range, the D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easier to service system of internally routed brake and derailleur cables.
6
Full Composite Fork
D-shaped steerer tube and legs are constructed entirely from Giant’s Advanced SL-grade composite for the lightest weight and superior handling.
7
PowerCore
A massively oversized bottom bracket area features a fully integrated 86.5mm wide design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
8
New Cable Routing
Frame and handlebar feature all-new cable porting for sleek, non-cluttered appearance and easier adjustability.
9
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.
10
Aero Handlebar/Stem
Aero handlebar and stem are designed to reduce overall drag while minimizing weight.
11
Aero Bottle Cages
Custom-engineered down tube and seat tube-specific water bottle cages help minimize overall aerodynamic drag.
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 Aero
Found inside the head tube of the Defy, Propel and TCR ranges, the D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easier to service system of internally routed brake and derailleur cables.
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.
RideSense Ready
This frame comes prepared to accept the Giant RideSense sensor and accompanying hardware.
Vector Integrated Seatpost
The integrated vector seatpost saves weight compared to standard composite posts, while improving aerodynamics and adding road-smoothing compliance.
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.
