Every second counts. Giant's Trinity lets you slice off those precious seconds and set PRs along the way. The Trinity features the perfect blend of a stiff aluminum frame with a forgiving carbon fork for a ride that's efficient and aerodynamic. Time-trialists, multi-sport athletes and weekend superstars will appreciate the light aero wheels, the wind-cheating aero seatpost and the aggressive aero bars that let you keep your wind-cheating tuck. Plus, Dura-Ace bar-end shifting and Vision TRIMax cranks keep your cadence high and your competition low, too.
