Now even faster, this aero rocket-ship is built for speed when it matters most. The re-engineered frameset is even more adept at slicing through wind, and its also lighter than the previous generation. The result? Race-winning efficiency thats hard to beat.

Integrated aerodynamics

AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimises aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and Contact SLR/SL Aero cockpit produce the best overall aero performance.

Easier adjustability

All-new cable routing through the handlebar and frame makes it quicker and easier to adjust or change cockpit components and fine-tune performance and riding position.

Race-winning efficiency

Advanced-grade composite frameset features high-performance materials and proprietary manufacturing processes. As a result, its now lighter than the previous generation for an improved stiffness-to-weight ratio.

Technologies

Advanced Composite Technology

Giants High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.

AeroSystem Shaping Technology

Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance.

Tubeless System

Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.

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.

PowerCore

A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design (92-millimeter wide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.

Vector Seatpost

This full-composite, lightweight and highly aerodynamic seatpost is engineered specifically for performance road riding.

RideSense Ready

This frame comes prepared to accept the Giant RideSense sensor and accompanying hardware.
