The Felt AR4 is a road bike with an aerodynamic UHM carbon fiber frame. This is similar to the Felt AR3, but uses Ultra High Modulus (UHM) carbon fiber rather than the Advanced MMC, and has a number of different components used in the assembly. The fork is built to match the frame, with an aerodynamic design using UHM carbon fiber in the blades, crown, steerer tube and fiber dropouts weighing a total of 450 grams. Both the drivetrain and the brakeset are made up of Shimano Ultegra parts, and the wheelset uses Felt AeroR2 700c rims with a CNC machined braking surface. As with all Felt AR bikes, an aerodynamic design is used in the construction of the frame to offer almost a full 2% advantage over round tube shapes.
