Every second counts. Giant's Trinity A2 lets you clean up on the competition without being taken to the cleaners. The Trinity frame features the perfect blend of composite and aluminum for a ride that's efficient and aerodynamic. Time-trialists, multi-sport athletes and weekend superstars will appreciate the light Xero wheels, the wind-cheating carbon aero seatpost and the aggressive aero bars that let you keep your wind-cheating tuck. Plus, Shimano bar-end shifting and FSA cranks will keep your cadence high and your competition low, too.
