For the last few months I've been building my first fixed gear bike. The problem I have is the chain lenght. I've chosen a 48x17 ratio but with the chain installed, the axle sits just past the front of the dropout (horizontal) when the chain is tight. When the chain is slack, the axle isn't completely in the dropout. If I and a full link, there is too much slack and I bought a half link but it was stiff when connected. So I don't want to use a half link. I've read most don't last long.
What I want to know is will a change to a 46x16 ratio give me enough lenght? BTW, my chainstay lenght is 16". Sorry if I rambled on too long.
