Your competitors will be envious when you show up on your Speed Concept 9.8 WSD. One of the most-advanced aero bikes, its Trek carbon frame boasts Kammtail shaping that cheats the wind even in cross winds. Plus the truncated shape is lighter and stiffer for excellent acceleration and cornering. The Speed's unparalleled aerodynamics is also courtesy of ingeniously hidden cables, brakes, wheel quick releases and even the computer sensor. This clock-beater features SRAM's precision Force components, too. Plus, 50mm-profile Bontrager Aeolus wheels that fly down the road and Trek's WSD sizing just for women. Your PRs will never be the same.

Three years in the making, Trek's Speed Concept takes revolutionary design paired with a groundbreaking aero shape to make the cleanest integration of brakes, cables, and electronics ever seen on a bicycle. It's the fastest way to the finish. (Click images to enlarge.)

Cross winds greatly affect the aerodynamics of a bike. Most TT bikes have low drag when the wind is straight on, but in the real world, it's almost always a cross wind. The Speed Concept's Kammtail shape maintains its full aero benefits at any yaw angle. The result? Your bike is faster in any situation. Look Ma, no cables. You can look for the brake and shift cables, but you won’t see them—and neither will the wind. Cables contribute a massive amount of drag, and routing them internally through the bars and frame eliminates that drag and maximizes speed. Speed Concept is the first bike with front and rear brakes actually built into the fuselage. This innovative setup results in less drag and cleaner lines—a faster, sleeker, better solution.

Even the quick-release skewers on the Speed Concept increase its speed. Trek integrates them into the shape of the bike for faster aerodynamics. Computer sensors create unwanted dirty air—but not if you build them seamlessly right into the frame. Speed Concept is the first TT bike to integrate electronics into its aerodynamic shape. Out of sight, out of the wind. The minimal frontal surface area of Speed Concept, combined with its svelte shape, makes the bike slice through the wind effortlessly, so more of the power you apply to the pedals translates directly into speed.
