Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
Now even faster, this aero rocketship is built for speed when it matters most. The reengineered frameset is even more adept at slicing through wind, and it’s also lighter than the previous generation. The result? Race-winning efficiency that’s hard to beat.
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/SL Aero cockpit produce the best 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-grade composite frameset features high-performance materials and proprietary manufacturing processes. As a result, it’s now lighter than the previous generation for an improved stiffness-to-weight ratio.
AeroSystem Shaping
Advanced Composite
High-performance grade raw carbon material is used to produce this custom material in our own composite factory with a high stiffness-to-weight ratio.
Aero Tubeless WheelSystem
Engineered with proprietary Dynamic Balanced Lacing technology, this composite aero WheelSystem and tubeless tires deliver superior efficiency, pinpoint control and superior aerodynamics.
Vector Seatpost
This full-composite, lightweight and aerodynamic seatpost is engineered specifically for performance road riding.
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.
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.
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.
New Cable Routing
Frame and handlebar feature all-new cable porting for sleek, non-cluttered appearance and easier adjustability.
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.
Aero Handlebar/Stem
Aero handlebar and stem are designed to reduce overall drag while minimizing weight.
Aero Bottle Cages
Custom-engineered down tube and seat tube-specific water bottle cages help minimize overall aerodynamic drag.
