Dear Tom,

Here's the link that James Thomson recently posted to the details of
Merckx's hour bike:

Mexico City is at about 7,350 feet, so yes a rider will go noticeably
faster. The defaults for this calculator predict 22.77 mph at sea
level:

Raise the elevation to 7,350 feet and the speed prediction rises to
25.19 mph, about 10% faster.

Someone who pedals daily around the Arkansas River at about 4,900 feet
enjoys a predicted 24.36 mph and a 1.6 mph advantage.

Of course, thinner air might reduce the rider's aerobic function and
power.

Cheers,

Carl Fogel
