The F-90 is the most advanced custom racing bicycle Lightning makes. This amazing machine has broken records and bested bikes in classes above its own.
The latest version of this machine as used in RAAM 2004 uses the R-84 frameset with Lightning carbon cranks, 33 to 160 inch gear range, and disc brake. The fairing is an exotic Kevlar composite nose and hard shell tail section with Kevlar and Mylar sailcloth middle section. The sailcloth does not stretch like Spandex but can still be pulled tight to approximate a full hard shell fairing. It also incorporates zippers for entry, exit, and cooling. The final component is a long windshield which tilts forward for entry and exit, or visibility in poor conditions. The long windshield can be replaced with an short windshield for hot rides or foggy/rainy conditions. The separate short windshield is included with the F-90. The windshields pop on and off with a single quick release pin.
The F-90 is a super fast machine that can be ridden on the street (with a mirror), plus only weighs 30 pounds for fast climbing! The extreme performance of this machine is not for the faint hearted or slow reacting. If you have The Right Stuff and $14,000, you can have the fastest bike in your state!
Obviously, aerodynamics are important on flat and down-hill sections, but aerodynamics can play an important role on moderate hills and rollers. Check out Gerry Pease’s analysis of the balance between aerodynamics and weight.
