    Granny Gear Tensioner

    I converted a cool 531 shwinn moab to single speed for a costme of the shop I work at. Well anyhow I was not having anyluch finding that magic ratio.

    I rembered seeing a Pic of someone useing a granny gear as a tensioner.....

    You place it between the chain just after the cog. Works super! I can run a 32x16 no problem. I think I used a 22 thooth granny I even recycled that granny off her crankset. I was trying to build this on the cheap for her. I think this would work for a fixie to. You just have to have some pertty goog clearance on the chain stay so that ring doen't hit anywhere.

    Just another option for those doing it on the cheap.

    I have seen street performers on tall unicycles - like 10 feet! - use two floating rings as tensioners for the long chain.
