We just bought a house in Clermont/Lake County. There are hills there but nothing of any bother. We are running stock Santana 10spd gearing (11/34 cassette and 30/39/53 rings) and just about never use the inner ring. Even touring in Germany or riding the hilly parts of Maryland and Pennsylvania that small ring gets pretty lonely (39x34 is a pretty low gear for us).
We are used to the way the thing shifts and have ridden it in Lake County with no issues. Is there any real advantage to switching to a narrower range cassette or taking the 2 inner rings off and just running the 53?
