Just a suggestion, but if you're changing the chain and both sprockets, you may want to consider going to a 520 chain with a sprocket combination that gives you a similar final ratio to the sprocket combination you listed (which is a 2.813 ratio). A 520 chain and sprockets are considerably more robust and will last longer. Combinations of 520 sprockets that would be close to the same final gearing would be 12/34 (2.833 ratio) or 13/37 (2.846 ratio). Just buy a 115 link, or longer, 520 chain and cut it to fit as needed.
