comment How do I train to gain Tony Martin/Fabian Cancellara/Bradley Wiggins esq abilities to turn over a big gear 58t, 11t,?
This is an overly broad question and the answers would then also be overly broad and thus wouldn't particularly fit in the Q-and-A format. Can you narrow your question to something more specific?

comment Are 130 BCD chainsets stiffer than 110 BCD?
I'm slightly confused by your question. You mean for the same size chain rings, like 52-tooth or 39-tooth? Or do you mean a 34-tooth chain ring on a 110 BCD crank vs. a 39-tooth ring on a 130 BCD crank but with corresponding differences in the rear cogs so that the overall gear ratio is held constant? What is the comparison you're trying to make? (BTW, for the same power input and cadence at the crank, force on the chain ring is inversely proportional to the number of teeth on the chain ring, so a 34-tooth chain ring carries 39/34 = 1.15 ==> 15% more force than a 39-tooth ring.)

1899, at 63+ mph, by Charles "Mile-a-minute" Murphy. The current absolute speed record is held by Fred Rompelberg at 167 mph. He used a double reduction gear (70/13 connected to a 60/15 for a total gear ratio of 21.5) and his wheels were 18 inches in diameter.

comment How are the categories for climbs decided?
I used the official TdF website for the name of each climb, its category, length, and gradient. Given those data, it's simple to calculate the elevation contours.
