From Ironman distance triathlons to shorter efforts against the clock, give yourself a true advantage in speed and aerodynamics. This super-efficient composite machine gives you everything you need to chase a new PR.
Built with Advanced-grade composite materials and engineered with AeroSystem Shaping Technology, this frameset improves aerodynamics in real-world triathlon conditions. Its AeroSystem Shaping means that every tube shape is designed to minimise drag no matter which direction the wind comes from. The Contact base bar offers maximum adjustability, so you can dial in your perfect position for comfort and performance. And the SpeedControl brakes offer confident control without sacrificing aerodynamics. PLEASE NOTE THIS BIKE IS NOT UCI LEGAL DUE TO THE DESIGN OF THE FORK.
Key Performance Factors
Extensive CFD analysis, dynamic wind tunnel testing, and triathlon-specific design result in superior aero performance in a race-ready configuration.
Everything from the frame shape to the aero seatpost and brakes are engineered to perform as a system.
Refined frame geometry and a wider range of adjustability allow for a triathlon-specific fit that’s designed to meet the unique demands of multisport racing.

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.
Every effort has been made to ensure accuracy throughout this website. However, Giant reserves the right to change bike specifications, features, prices and colours without prior notice.

Advanced Composite Frame
High Performance-Grade raw carbon fibre and Giant’s proprietary resin formula are used to produce custom composite material in our own composite factory. Extremely lightweight, stiff and compliant.
Advanced Grade Hybrid Fork
Advanced-grade composite legs and an alloy steerer tube deliver a lightweight design and precise steering.
Aerosystem Shaping Technology
Through CFD and dynamic wind-tunnel testing, engineers optimize each tube shape to deliver superior aerodynamic performance.
Contact Base Bar
Giant’s Contact base bar configuration offers maximum adjustability and ease of use.
A massively oversized bottom-bracket/chainstay area features a fully integrated, 92-millimeter-wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.

Technologies & 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 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.
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.
