Another question, how do the ratios come into play? My wheelset is 16 teeth, the crank is 160mm with 46 teeth. If I increased the size of my crank (ex. 170 and 48t), that would mean I would be able to go faster but building up initial momentum would be harder?

I see the description of the crank says I can only use a size: 1/8" chain (not 3/32). Will a 1/8" chain work with my wheelset?
