Race day or training day, Felt's IA 2 gives you an unfair advantage over the competition. The heart of this triathlon bike is an exceptionally aero, high-modulus carbon frame with deep-section frame tubes and Felt's own integrated Dagger stem and fork to pierce the wind. Felt provides a pair of their own carbon deep-section rims and fast-rolling TTR tires to relentlessly trim down your ride time. Shimano's flawless Ultegra Di2 drivetrain is used to exceptional effect, with rapid, crisp shifts from the extensions or the bullhorns. And, since a comfortable rider is a strong rider, the IA 2 comes spec'd with a supportive ISM Adamo Attack saddle, a completely adjustable Felt Aero Tri seatpost, and Felt's carbon Dagger Ultimate base bar and f-bend extensions.
