Felt DA2 (2014)

Years of research, engineering and wind-tunnel development went into the DA2, and the results are obvious. The DA is the weapon of choice for time trialists like Kristin Armstrong and Patrick Gretsch as well as triathletes like Terenzo Bozzone and Andi Bocherer. With Felt Dual Aero TT / Tri UHC Advanced carbon—shaped through extensive Computational Fluid Dynamics engineering and real-world testing—it’s 14% more aerodynamic and 13% stiffer than the previous-generation DA. The DA2 features the all-new Bayonet 4 steering system with integrated front brake and is optimized for Shimano Di2 11-speed electronic shifting, internal cable routing and an integrated battery mount. When every second counts, go with the DA2.
