For some reason, the shop here starts at 44T (-12%), and charges US$35 to change it to the regular (52T?). Singapore is relatively flat (we only have a few decent hills and no mountain to speak of).
I can't say I'm very fit, though I do very light running/cycling/swimming several times a week. I'm wondering if I should go with the regular gearing or stick with the lower one?
From some reviews online it seems the -12% is fine for city transport. Anyone has a good experience with it?
