Giant 2027 Propel Advanced 2 – Shimano 105

Product Overview

Get the most from your hard-earned pedaling power. Whether you're squeezing out more speed on solo rides or taking bragging rights in the group, the new lighter, smoother Propel Advanced makes the thrill of road speed accessible to all.

The 2027 Propel Advanced 2 is the fourth generation of Giant's legendary aero road platform—completely reengineered to deliver the perfect balance of instant acceleration, sustained efficiency, and top-end speed. Built around an Advanced-grade Composite frameset with AeroSystem Shaping technology, this bike is faster, smoother, and more efficient than ever before.

The frameset is lighter than the previous generation with greater torsional and pedaling stiffness, so you feel instantaneous reaction when you make your move. With Shimano's proven 105 12-speed mechanical shifting, 38mm alloy wheels, and tyre clearance up to 32mm, the Propel Advanced 2 is the perfect entry into world-class aerodynamic performance.

Key Performance Factors

⚡ Instant Speed – Explosive Acceleration

• Frameset is lighter than the previous generation with greater torsional stiffness and pedaling stiffness

• You feel instantaneous reaction when you launch an attack or sprint for the line

• Advanced-grade Composite front triangle assembled and molded as one continuous piece via Modified Monocoque Construction

💨 Sustained Speed – Smooth, Fatigue-Free Ride Quality

• Vector seatpost offers greater compliance compared to the previous generation

• Composite fork and integrated cockpit absorb bumps and vibrations up front

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

🏆 Top-End Speed – Unified Aero System

• AeroSystem Shaping with truncated ellipse tubing reduces drag more effectively than traditional teardrop shapes

• Developed and proven through CFD modeling and wind-tunnel testing at a wide range of yaw angles

• Frame, cockpit, wheels, and tires form a unified system that lowers total resistance at high speeds
