  • Think the Speed Concept is just a one-off? Think again. Yes, it's a team-only item at the moment but Trek definitely has plans to bring this market no later than the 2011 model year.

  • The Speed Concept's unique Kamm tail shaping uses an abruptly chopped tail for the back of the fork blades, down tube, seat tube and seat stays.

  • The bottom bracket area is particularly bulbous-looking from the front and features Trek's BB90 integrated bearing system.

  • According to Trek, the Kamm tail truncated airfoil (second from right) behaves identically to a full 8:1 cross-section (far right) and markedly better than a 3:1 section (second from left), especially at higher yaw angles. And in spite of appearances, there is no additional stub mounted to the end of the Kamm section; the airflow just makes it look like there is.
