Propel Advanced SL Frameset
ULTIMATE SPEED
Speed is a sensation. It’s a feeling that varies from ride to ride in countless different ways. Flat roads or mountains. Solo rides or in the group. Competition or fun. That’s the idea behind the new Propel Advanced SL frameset. It's engineered to deliver not just speed, but every type of speed.
Key Performance Factors
INSTANT SPEED
In the moments when explosive speed matters most—launching an attack, chasing a break, or sprinting for the finish line—the new Propel Advanced SL is quicker and more dynamic than ever. The new frameset is more efficient with 14.2% more torsional stiffness and 14.8% greater pedaling stiffness—so you feel instantaneous reaction when you make your move.
SUSTAINED SPEED
Engineered for full-bike compliance, the new Propel Advanced SL frameset delivers a significantly smoother ride when you’re rolling in the group or piling up training miles. The Vector integrated seatpost has 25% greater compliance compared to the previous generation. The fork helps absorb bumps and vibrations up front. And additional tire clearance allows for high-volume tires up to 32mm, further smoothing out the ride to help you maintain higher speeds with less fatigue.
TOP-END SPEED
The frameset, including the frame, fork, Vector integrated seatpost, and aero bottle cages, are designed to be part of a system to lower total resistance when you’re pushing high speeds in the wind—whether you’re on a solo break, taking pulls at the front, or powering away on a climb. OverDrive Aero technology includes a slim, tapered head tube paired seamlessly with a D-shaped fork steerer tube and spacers. Brake and shifter cables can be internally routed through the frame and fork, keeping them hidden from the wind.
Highlights
1
AEROSYSTEM SHAPING
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.
2
ADVANCED SL COMPOSITE
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.
3
ONE-PIECE MOLD
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.
4
FULL COMPOSITE FORK
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.
5
OVERDRIVE AERO
The D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easy-to-service system of internally routed brake and derailleur cables.
6
INTERNAL CABLE ROUTING
The frameset is designed with ports and channels to keep cables hidden from the wind while allowing for easy adjustability.
7
AERO BOTTLE CAGES
Custom-engineered down tube and seat tube specific bottle cages help reduce overall aerodynamic drag.
8
VECTOR INTEGRATED SEATPOST
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.
