Not to mention the price- at my frequent local supplier, a 53t Zen chainring (biggest in my pouch) is ¥19,800. That's already spendy in my book. A 63t is ¥51,300! Who is paying that for chainring???
One of my friends is doing his f200 qualifiers on 130" (but he's a freak of nature) and Nicholas Paul just rode a mammoth gear to a near WR time in the f200 at Aguascalientes - the footage I saw wasn't great but my rough calculation was 137"-ish. Pursuiters are also putting bigger rings on to accommodate larger cogs, so I think it's a mixture between the top guys beasting the gym harder and also looking for those marginal gains in efficiency.
