I have a 9 spd, just bought the kit to turn it into a 13. I like 13s for the same reason you stated above. My question is regarding MPG consumption, did you notice a difference after turned into 13 in mpg consumption compared to when it was a 9 spd?. I guess it would help having more range less lugging and maintaining momentum when going through hills but not sure. Just wondering
