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 minimize 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.

Key Performance Factors

Aero efficiency

Extensive CFD analysis, dynamic wind tunnel testing, and triathlon-specific design result in superior aero performance in a race-ready configuration.

Integrated design

Everything from the frame shape to the aero seatpost and brakes are engineered to perform as a system.

Perfect fit

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.

WeightThe 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.
