So I've been riding fixed gear for about a year now (46 x 16) and its alright, except where I live is REALLY flat -- so I could use a little more power. Would 48 x 16 give me much of a difference? Or should I upgrade to some racing cranks and go 50 or 52?
I don't skid stop (I know I know ... wuss) so I'm not worried about that -- but should I go down to a 15 or up to 17 for other reasons?
