Key Performance Factors

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 the best overall aero performance.

Easier adjustability

Cable routing through the stem and head tube 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 Giant’s pro-level composite materials and manufacturing processes. The result is 150 grams of weight savings compared to the previous generation and an even greater stiffness-to-weight advantage.

TECHS & FEATURES

×

ADVANCED COMPOSITE TECHNOLOGY

Giant’s 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 moulded 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 optimise each tube shape to deliver superior aerodynamic performance.

×

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.

×

TUBELESS SYSTEM

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

INTEGRATED SEATPOST

Designed as a key performance factor in the overall frameset, the integrated seatpost saves up to 40 grams compared to standard composite posts, while improving aerodynamics and adding road-smoothing compliance.

WEIGHT
The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
