i don't see how the headtube and fork tines represent 3% (plus the small amount added by the rest of the frame that's caught at a 10 degree angle) of the total frontal area exposed to the wind by rider and bike. and if it did it would have to be removed completely, not just reshaped. and even then the vast majority of the wind would STILL be caught by the rider's frontal area. in any case, it would be a small fraction of 3 percent. maybe three percent of three percent.

lies, damned lies, and statistics...
