Gearing has obviously changed the way cycling is done in the mountains. Coppi's 46/18 (or even 46/20) would have been over-geared in the Merckx-Hinault era when 42/21 (or 22 or 23) would have been the norm. Which is over-geared compared to the 39/25 (or 26, 27, or 28) setups now in use.
Records on Alp D'Huez over the years are problematic because there has been no official starting line.
it would be quite interesting to take coppi's effort at pushing those tanks up rough surfaced mountain roads and then place the cyber coppi on a compact. i'd have to figure coppi would be more than up to the task against modern riders.
