Our entry-level TT/Tri bike begins with our Aero Superlight Custom Butted 6061 aluminum frame with ovalized top, down and seat tubes for improved aerodynamics. Matched to that is our Aero TT/Tri UHC Performance with carbon fiber blades. The parts pick includes 105 derailleurs and Felt TTR4 wheels. Few bikes offer such a great combination of aerodynamics and value.
