52t front chainring, 30mm tires on wide rims, and what looks like a 10-33t cassette. 172.5mm crank?
I'm curious how that gear range compares. By my calculations, his easy gear is equivalent to about a 39t x 25t, which is reasonable.
I'll paste a gain ratio comparison chart below comparing to a 48t x 9-42t (Campy Ekar) which I like, but that 9t and even 10t are just too much friction for racing, so I add in a 58t x fictional/dream 13s 11-50t for lower friction and because I think that'd be my dream set up that would cover me for 55+mph descents and and HC climbs at minimal friction... would the lack of a FD, the 11t minimum cog and reduced weight overcome the chain crossover friction/losses in power?
