Felt IA 2.0 Expert Ultegra Di2 Bike

The Felt IA 2.0 Expert Ultegra Di2 is a race-bred triathlon/time-trial machine built for athletes chasing speed without compromise. Its carbon frame and fork built from Felt’s UHC Ultimate + TeXtreme® material deliver a stiff, aerodynamic chassis engineered to slice through wind while still providing race-day durability.

Equipped with full Shimano Ultegra Di2 electronic 12-speed shifting and Dura-Ace brake levers, this build offers razor-sharp shifting under load. Hydraulic disc brakes with 140 mm rotors provide powerful, reliable stopping in all conditions. The bike comes with Felt’s Dagger Direct 2.0 ASC aerobar/stem combo, extensions by Devox Ergomod, and an integrated IL 2.0 VM seatpost to let you fine-tune fit while maintaining aero efficiency. Tires are competition proven: Continental Grand Prix 5000 in 700×25c, paired with tubeless-ready Ultegra WH-R8170 wheels to keep weight and rolling resistance low.
