3.25hrs z2/z3

so i got a compact crankset from my in-laws from xmas, they happened to see it on an amazon wishlist. I was actually on the fence about it, still am. The couple of times I rented bikes with compact setup, I do recall liking the 50, but I don't know if it's really all that different from 53 (although I tend to use 38 a lot more than I use 53, so maybe that's saying something). I'd have to get a new BB so I won't be trying it anytime soon if I do decide to keep it
