Building on the previous bike’s Kammtail Virtual Foil (KVF) aerodynamics, storage integration, and adjustability, the new Trek Speed Concept’s design drops nearly a pound in frame weight – saving the rider up to 148 seconds (2 mins, 28 secs) on an Iron-distance bike course in comparison to the orignal Speed Concept according to Trek.
By testing in the wind tunnel using this real data, Trek reduced the frontal area of the bike, deepened the fork profile, refined the KVF tube shape, and retained the cross-wind performance KVF is known for, all while removing a whopping 437g from the frame. All cables and housing are completely internal on the new Speed Concept, and it includes an internal battery option for electronic drivetrains.
The cockpit’s frontal area alone was reduced 30%, while simplified adjustment points reduce the amount of hardware and simultaneously increase the range of fit positions. According to Trek, the integrated brakes are both easier to work on, and provide more stopping power, particularly on the rear where the new Speed Fin brake booster doubles as a wheel faring that saves ten grams of drag.
The new Speed Concept’s storage solutions make the rider faster when used together, with the Speed Box 2 storing a full flat repair kit or tubular behind the seat tube and extending the airfoil design.
The Two Pack Aero ‘leaves saddle bags in the dust’ by holding two bottles and tons of storage space above and behind the rider’s saddle. Here, according to Trek, this can save 253 seconds on an Iron-distance bike course when combined with the Speed Concept’s other storage solutions.
