Unleash your sprint with 200 meters to go. Close a gap, chase back, launch a solo attack. This new aero road machine is made for the moments that count. More aero, more adjustable, more ways to win.

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 Aero cockpit produce outstanding 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 SL-grade composite frameset features Giants pro-level composite materials and manufacturing processes. The result is 225 grams of weight savings compared to the previous generation and an even greater stiffness-to-weight advantage.

Technologies

Advanced SL Composite Technology

Professional Grade raw carbon fiber is woven in our composite factory to produce our lightest, stiffest and highest quality frames. This is the technology used by Giants pro racers in almost every cycling discipline.

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 Integrated Seatpost

The integrated vector seatpost saves weight compared to standard composite posts, while improving aerodynamics and adding road-smoothing compliance.

RideSense Ready

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

Power Halo

Power training shouldnt be a mystery to be solved only by the pros with expensive equipment. Easy to set up, easy to use and easy to read, the all-new Power Halo is bringing metric-based training to all riders.
