2007 Schwinn Fastback Specifications
-
Frame and Fork
-
The 2007 Schwinn Fastback used a TIG-welded aluminum frame blended with lightweight carbon seat stays and Schwinn Black Label Carbon Pro fork with Chromoly steering tube. The fork steering tube diameter measured 1/8 inch. The Fastback frame was available in small, medium, large and extra large. The frame incorporated a sloping top tube for easier mounting.
Cockpit
-
The Fastback featured a road-tuned handlebar and stem joined to the fork via an FSA IS-3 integrated headset. The road-tuned handlebar allows a rider to crouch in a more aerodynamic position during operation of the bicycle. The model included a Selle San Marco Ponza saddle coupled with a 27.2 mm diameter aluminum seat post. Shimano Tiagra brake levers and Tektro RX 40 caliper brakes provided the bicycle's stopping power.
Drivetrain
-
The 2007 Schwinn Fastback included a Tiagra front derailleur, Shimano 105 rear derailleur and front and rear Tiagra STI gear shifters. STI, or "Shimano Total Integration," is a design of shifter that incorporates both braking and gear shifting functions in a single control. The design allows hands to remain on the handlebar at all times when operating the bicycle. The Fastback is fitted with a nine-speed rear cassette and Truvativ Elita 50/36 crank mated to a Truvativ Giga X Pipe 68 mm English bottom bracket. Driven by a Shimano CN-5600 chain, the nine-speed rear cassette and double chain ring crank gave the Schwinn Fastback Comp a total of 18 possible gears.
Wheel and Tires
-
Schwinn Fastback wheels were comprised of Alex RB500 rims connected to Formula RB hubs via black steel spokes. A Schwalbe Blizzard 700x23c tire cushioned each wheel. Wheels were held in place by quick-release skewers. Eliminating the need for a wrench, the quick-release skewer design allows a wheel to be effortlessly removed from the bicycle in the event of a flat. Fitted with presta valves, Schwalbe Blizzard tires are inflated using a presta valve-compatible bicycle pump.
