From the same mold as the IA, the IA 2 offers the same aerodynamic advantages of the IA FRD. Constructed from Integrated Aero Tri UHC Advanced carbon fiber and equipped with Shimano Di2, the IA 2 is race ready. This bike was a demo. We did remove the DA crank and reinstall a new Ultegra crank. This was the IA 2 that came with DA parts, not the current IA 2 that has full Ultegra Di2.
