I am rebuilding an old road bike (new to me) and am about to put on a new chain. I was doing the calculation to see the length of chain needed and got to thinking maybe the current gear ratio is not right for me and I should address that before cutting down the chain. The chain rings are 52/42T and the 6-speed freewheel is 13-24T.
This is my first bike since I was a kid and got the bike to ride for recreation at a pretty leisurely pace. I'd like to use the bike in somewhat hilly (and scenic!) areas, am in my mid-twenties, and would consider myself to be in average shape. Is a 42:24 gear ratio low enough for any climb I'll ever face or should I opt for a different freewheel? Again, I'm not looking to power my way up any hills -- just want to make sure I'll be able to climb hills period.
