My old(recently sold) Clifcat frame w/its low seating, was good for getting "SPEEDING TICKETS". Downtown, there is this hill(street), that is about 5 blocks long. It starts out at top about a 45 degree angle, then goes to a 30 degree. When I had a computer on the Clifcat(properly calibrated of'course), I went down it in a sqaut/tucked-in(crotch-rocket) position(for least wind resistance), and at the bottom, the max speed read: 54.7MPH!!! The hill is limmited to 20MPH, and the intersection at bottom has a trafic light! Near the bottom, My heart skipped a beat when I had the breaks on hard for the red light, and my front wheel went over a man-hole cover. The front wheel locked and skidded a bit before rectaining traction! When I heard that skid, I thought I was going over the bars for sure(at 20MPH w/a car 50 feet behind me)! Man was that FUN!!!
