I'm upgrading from my old (80s) 12 speed.
The bike I'm looking at has a 11-25 sprocket and I can choose either a 46x36 double, a compact (50x36) or a standard double (53x39).
I'm not sure which I would choose. Currently my biggest gear is 52 front and 14 rear. I use that about 15% of every longer ride. I live in florida (but not forever) so no major downhills. What are your opinions of which crankset I should use?
