Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Chain Tension Affected by Changing Sprocket?

I've got a 46/16 gear ratio ratio right now and I want to make it a bit higher. I'd go with a 15T or 14T rear sprocket but I want to know how drastically that'll affect the chain tension. Input?

each tooth difference means the axle will need to move 1/8" back or forward:

You set chain tension. Its not determined by your ratio.
