Real-world testing gives you real-world results with Trek's Speed Concept 9.5. Its lead just got a little larger with a US-made carbon frame that uses slippery Kammtail tubing. Those tubes are lighter, stiffer, and more aero than traditional designs, even in cross winds. On this rocket, nothing was overlooked: internal cable routing, hidden quick releases, and built-in brakes, computer sensors, even integrated storage, and computer mounts are all designed for aerodynamic speed. And, it's one of the most adjustable bikes available, so dial in the perfect tuck and push out every watt. Of course, the 9.5 is built for with top-end specs, with 11-speed Ultegra, carbon TT bars and frictionless Race Lite wheels.
