Details

TTs are one of the ultimate tests. The wind conspires against you, the sun bakes you and the never-yielding clock just keeps ticking away. Trek's Speed Concept 7.8 is your only friend in this harsh world. This full-carbon secret weapon uses unique Kammtail shapes that actually make you faster even in cross winds. Of course Trek tuned the carbon so it's exceedingly stiff where you need it to be and compliant where you want it for comfort. Then they hid the rear brake, cables, quick releases and even your computer sensor from the wind. Plus, the specs are all aero, all the time, too, with slippery Bontrager Aura 5 wheels, carbon aero bars and extensions, and a carbon seatpost. Then they top it off with a 20-speed SRAM Force drivetrain with TT shifters. You can only count on yourself out on the course, and your Speed Concept.

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. The Speed Concept's rear brake is 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. The 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 the 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.
