Giant 2027 Propel Advanced SL Frameset

Product Overview

From breakaways to the final sprint. The reengineered aero platform that maximises every watt.

The 2027 Propel Advanced SL is Giant's most advanced aerodynamic road frameset yet. Completely reengineered as a unified system, it delivers the perfect balance of top-end speed, instant acceleration, and sustained efficiency—whether you're attacking on a climb, driving a breakaway, or sprinting for the line.

Available as a frameset with fork, seatpost, and cockpit integration, the Propel Advanced SL sheds 355g from the previous generation while gaining 14.2% more torsional stiffness and 14.8% greater pedalling stiffness. The result is a frameset that feels instantaneous under power, yet remarkably smooth over long distances—the definition of a modern aero all-rounder.

Key Features

🏆 Advanced SL Composite – Ultralight, High-Stiffness Carbon

• Professional-grade raw carbon woven in Giant's own composite factory

• Continuous Fiber Technology adds strength while minimising weight

• One-Piece Mold construction: a single bladder (vs. three in the previous generation) creates a one-piece front triangle—reducing weight without compromising stiffness or aerodynamic shaping

• Frame weight: 800g (size M, unpainted)

📐 AeroSystem Shaping – Proven in the Wind Tunnel

• Truncated ellipse tubing more effectively reduces drag than traditional teardrop shapes

• Developed and validated through CFD modelling and wind-tunnel testing across a wide range of yaw angles

• Total system energy savings of 18.4 watts—accounting for linear aero drag, wheel rotating drag, and tire rolling resistance

⚡ Instant Speed – Explosive Acceleration

• 14.2% more torsional stiffness and 14.8% greater pedalling stiffness than the previous generation

• Every watt translates into immediate forward motion

• The frameset reacts instantly when you launch an attack or sprint for the line

💨 Sustained Speed – Smooth, Fatigue-Free Ride Quality

• Vector Integrated Seatpost delivers 25% greater compliance than the previous generation

• Fork and integrated cockpit absorb bumps and vibrations with 15% added compliance up front

• Tyre clearance up to 32mm—run high-volume tyres for further comfort and speed with less fatigue

🔧 Full Composite Fork – D-Shaped Steerer

• D-shaped steerer tube and fork legs constructed entirely from Advanced SL-grade composite

• Ultralight weight, precise handling, and improved aerodynamic performance

• Increased tyre clearance up to 32mm

🛠️ OverDrive Aero – Easy Service, Hidden Cables

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

🎯 Internal Cable Routing – Clean and Adjustable

• Ports and channels keep cables hidden from the wind while allowing for easy adjustability

🍶 Aero Bottle Cages – Integrated Drag Reduction

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

🔩 UDH Compatible – Future-Proof Drivetrain

• SRAM UDH (Universal Derailleur Hanger) compatible for SRAM Full-Mount derailleurs

What Riders Are Saying

"The new Giant Propel Advanced SL hits the nail on the head for the aero all-rounder. But it adds something that aero all-rounders don't necessarily shine at: plenty of comfort." — Rennrad-News (120km test ride)

"The balance between lightweight, aerodynamics and handling is very hard to fault. The finishing of the bike is exceptional and the equipment levels are spot on." — 99 Spokes

"The latest generation of the Propel gets nearly everything right... Dipping below 6.8 kg and with a claimed 18-watt savings, the latest Propel edges into all-rounder territory." — 99 Spokes

"At 6.44 kg in the top version, it poses major competition to the TCR." — Mount7

"Overall movement is very smooth, with no strain. During cruising, the airflow feels stable—a frame that's easy to ride without disrupting your pedalling rhythm." — Y's Road Fukuoka
