Jeff Fox said:Today at lunch I was telling a friend about how I used to regularly
hit 60mph on a long downhill stretch of road. He said, "not
possible unless it's a super bike and you are Lance Armstrong".
Quoted message said:I rode a Sears brand 10 speed, nothing special. I was 16-17 years
old at the the time and rode 10-20 miles a day on a pretty regular
basis so I was in great shape. I had a cheapo speedometer that had
a wheel that meshed with the spokes. I never calibrated the
speedometer and never had a car pace me so I have no idea how
accurate the speedometer was.
Quoted message said:The bike was stable at top speed and I never crashed on that run.
I'd pedal as hard as I could in top gear and then coast during the
end of the run. The road took a pretty sharp right hand turn and I
had to slow a bit at the bottom to make the turn. Is it possible
that I really did hit 60mph on that crummy bike on that long steep
hill?
Quoted message said:This is not so much to prove him wrong, it's a silly argument and
not worth winning. I'm just wondering if it's really possible that
I was going that fast. Looking back I did not see it as that
extraordinary. Has anyone else done it and can prove it?
How did you determine you were going 60mph? When I first raced, we
had a guy in a Corvette follow the race who assured us we descended at
60mph, something that with the advent of accurate bicycle speedometers
turned out to be grossly false. That hill was worth 45mph at best.
Reaching 60mph on rare occasions (never passing up an opportunity when
it occurred) assured me that without a tailwind, or taking a flyer off
a 50- or more mph camper truck required at least a 13% grade... one
that is straight and smooth.
Typically, Sonora pass with its 20+% grades barely gets one up to
50mph because there are no straight steep sections. In general there
are so few straight steep roads that speeds over 50mph occur rarely.
My first such experience was on the Pso Rombo/Timmelsjoch pass from
Italy into Austria (?tztal). This is a classic Austrian steepy and it
has a convenient uphill runout after the chute just after he summit.
Tioga pass is not a fast descent, it having little more than an 8%
grade, but on the right day, with the right wind, and camper trucks it
can yield over 60mph. In all the years I have descended to Lee
Vining, such conditions occurred twice for me.
Bob Roll, professional racer, said he topped 60 two or three times in
his racing career.
