One of these days I'll do one with a 25-30mph lead out sprint. Doing it from 0 takes a lot out of a guy.

best I can get is around 37.5ish. I wonder if higher altitude really makes a noticeable difference...
I'm guessing he got the 40.5 off his cyclometer, not off the car mph.

Great job, but I sure wouldn't want to be riding right in front of a driver who is driving while videotaping at 40 mph.

Now, of course over the next few weeks I am going to try and see how fast I can go after a good warmup :-)

This is key. Next time I do this, it'll be at the END of my ride.

I won't talk though... Last time I checked I sprint at 34

That entertained me more than most of the drivel that comes out of Hollywood for millions of dollars.

I was disturbed by the fact that the person pacing you was trying to film you and the car's speedometer while driving.
I am glad there were no other cars around and I am glad you didn't have to stop/crash suddenly.

A buddy of mine wants to go to a compact crank too, good to know 36 mph is still possible (with the motor spinning hard.

My speedometer shows about 4-5 miles higher than my actual speed. ..... According the those police department radar speed signs they set up along the road now & then. It said I was going 40, and my speedo showed almost 45. You have to factor in car tire size, tire pressure blah blah
