Real-world testing gives you real-world results with the 2016 Trek Speed Concept 9.5. To bolster its performance, this aero rocket denies the clock with a US-made carbon frame that uses slippery Kammtail tubing. Those tubes are light, stiff, and amazingly aero, even in cross winds. On this rocket, nothing was overlooked: internal cable routing, hidden quick releases, 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 velocity with high-end specs, including 11-speed SRAM Force, carbon TT bars and frictionless Bontrager carbon wheels.
