❚ You are looking at the fastest UCI legal Tri / TT bike built today. Developed over two years, with careful use of NACA aerofoil profiles, CFD flow<br />
modeling and wind tunnel experimentation, the DA frame system delivers unsurpassed aerodynamic advantage with incredible drive-train and<br />
steering stiffness.<br />
❚ The DA features our revolutionary Bayonet Steering System which moves the steerer outside of the frame, improving steering stiffness 60%<br />
over a regular fork, while significantly reducing the aerodynamic drag on the bike.<br />
❚ The aerodynamic advantage does not stop with the obvious innovations of the frame: The Bayonet Steering System integrates an adjustable<br />
stem, which with refined frame geometry and the new <strong>Felt</strong> 3.1 carbon fiber multi-position seat post, allows a comfortable, laid-down, flat back<br />
riding position. Such a riding position can help you drop seconds on your personal best by enlisting less fasttwitch muscle fibers, and allowing<br />
smoother airflow across your torso.<br />
