Felt's F4 is a full-carbon road rocket that's ready to race, go for long rides or throw down on your training buddies. No matter how you're riding, Felt's Ultra Hybrid Carbon frame is ready to transform every pedal stroke into velocity. Yet this road machine is also refined, especially with the carbon fork turning rough roads into smooth ribbons of speed. The ride isn't the only impressive part though, a buttery-smooth Shimano Ultegra 22-speed drivetrain and cranks provides flawless shifting while the Shimano wheels slice through the wind and practically spin themselves up to speed. And, Felt's lightweight bars, stem and carbon seatpost complete this race-ready package.
