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 Giant bikes are designed for best-in-class weight and ride quality.


The all-new Trinity Advanced is built to help you achieve all your triathlon goals. From first timers to Ironman warriors, it has the aero engineering and adjustability to put you in the perfect position on the road. Built with Advanced-grade composite material featuring AeroSystem Shaping Technology, the frameset was developed and fine-tuned through extensive wind-tunnel analysis. The Contact alloy base bar offers adjustable comfort, and the SpeedControl brakes give you confidence and control without sacrificing aero performance.
