• use the inner ring of your crank, that should line up ok. only problem is it might only have 40 or so teeth (i use 42-16 fixed). you might be able to put the outer ring in the place of the inner ring, but that would probably be 50 or so teeth. you might want to use the smaller ring as its winter and its crap when you're riding into the wind up a big hill in the pouring rain with a high ratio!?
