The World's fastest UCI-legal TT bike - the Felt DA


You, the wind...and the finish line.

There is no greater measure of speed than the passage of time. Stop the clock sooner than the competition and it can mean only one thing: You were fastest. In an individual event, whether a Time Trial (TT) or Triathlon, there is no hiding. No drafting. Man and machine vs. elements. In cycling, a TT is known as the “race of truth”. Since the beginning, and for nearly 20 years, Felt has dedicated itself to making the fastest solo-effort bikes in the world. For 2009, that dedication and commitment—and the success that comes with it—continues.

Our design process is far and away the most time consuming and expensive in the business, but clearly yields the greatest results. After extensive internal brainstorming, detail rider meetings and feedback, and study in air flow and tube shape, we begin by creating modified NACA aerofoil profiles to guide our tube shapes to give the bike its maximum advantage over the wind. Before building a single prototype we use software called Computational Fluid Dynamics (CFD) to test the design in a virtual setting. This step helps remove much of the early trial-and-error. Once satisfied with a direction, we build a first prototype model for wind tunnel testing. This gave us the opportunity to refine our design for maximum performance. Bikes are tested both with and without riders, necessary adjustments are made, and, if needed, a new prototype is produced. And so on.

Many companies claim wind tunnel testing. The difference is our bikes are wind tunnel developed. There is a huge difference, and the result is clear: The Felt DA is the fastest UCI legal TT bike in the world. Only one bike on the planet can make this claim.

Look closely: Design innovations such a 1” head tube for reduced drag coupled with all-new Bayonet™ 2 Steering System which effectively moves the fork’s steerer outside the frame and increases steering stiffness by 60%; the chainstay-mounted brake which reduced aerodynamic drag by 4%; immediate top tube and all-points internal brake and shifter cable routing to aid in uninterrupted airflow; a front wheel confirming downtube to smooth airflow from the front wheel across the entire bike; horizontal rear dropouts to keep the rear wheel neatly tucked into the wheel well shaped seattube; and an aero seattube-conforming seatpost all add up to a bicycle design which is unparalleled.

On the competition front, the real-world results of Felt’s elite athletes reinforce what the wind tunnel has proven. Garmin/Chipotle-H3O’s winning TTT in the Giro d’Italia; the numerous major individual TT successes from team members including Christian Vande Velde, David Millar and Dave Zabriskie; Taylor Phinney’s World TT Championship, and any of the major events taken by Felt’s world-class tri team including distance athletes Tim DeBoom, Michellie Jones, Becky Lavelle, Andy Potts and Jordan Rapp. It all adds up to an undeniable aero reality.

Every TT/Tri bike in our line is outfitted with a full complement of go-fast parts. No matter what your budget is, we give each of our bikes as much aerodynamic advantage as possible to help you in your riding. With Felt, your best performance is just around the corner.
