Giant's Trinity Composite 1 W is built for speed, lots of speed. The Trinity's wind-cheating carbon frame offers the perfect balance between stiffness and comfort for maximum efficiency on every course. The carbon fork adds to that efficiency and steers with precision. The rest of the parts are just as fast. Time-trialists, multi-sport athletes and weekend superstars will appreciate the light Shimano wheels, the wind-cheating aero seatpost, the custom Giant hidden brakes and the speedy aero bars that let you keep your wind-cheating tuck. And, the Dura-Ace/Ultegra drivetrain keeps you cranking with silky smooth shifts and in front of your personal record.
