Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.
Propel Advanced SL Frameset
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.
Highlights
The Propel Advanced SL frameset 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, while the integrated seatpost reduces weight, improves aero performance, and adds road-smoothing compliance. This special edition honors Team Jayco AlUla with the team’s bold colors.

AeroSystem Shaping
2
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
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.
4
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.
5
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.
6
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.
7
New Cable Routing
Frame features all-new cable porting for sleek, non-cluttered appearance and easier adjustability.
8
Aero Bottle Cages
Custom-engineered down tube and seat tube-specific water bottle cages help minimize overall aerodynamic drag.
