Felt IA 2.0 Expert Ultegra Di2 Bike Info

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.

Hydraulic disc brakes with 140 mm rotors provide powerful, reliable stopping in all conditions.

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.
