Propel Advanced SL Frameset

Strategically engineered airfoil sections use truncated ellipse tubing to more effectively reduce drag compared to traditional teardrop shaped tubes. The system is developed and proven through CFD modeling and wind-tunnel testing at a wide range of yaw angles.

Professional-grade raw carbon is woven in the Giant composite factory using the most advanced engineering and construction methods. Continuous Fiber Technology adds strength and minimizes weight.

Proprietary construction technique uses a single bladder (as opposed to previous generation’s three bladders) to create a one-piece front triangle. The result is reduced weight without compromising stiffness or aerodynamic shaping.

D-shaped steerer tube and legs are constructed entirely with Advanced SL-grade composite for ultralight weight, precise handling, and improved aerodynamic performance—along with increased clearance for tires up to 32mm.

The D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easy-to-service system of internally routed brake and derailleur cables.

The frameset is designed with ports and channels to keep cables hidden from the wind while allowing for easy adjustability.

Custom-engineered down tube and seat tube specific bottle cages help reduce overall aerodynamic drag.

Designed as a key performance factor in the overall frameset, the integrated seatpost saves up to 45g compared to standard composite posts, while improving aerodynamics and adding road-smoothing compliance.
