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)

You need to consider what kind your cranks use (ISO or JIS square taper, Isis, Octalink), the spindle length and the BB shell length (68mm or 73mm). If this is over your head then take it to a bike shop. Once you find the right size for your needs, you have to select from the whole gamut of quality for a given size - for instance basic Shimano sqaure taper vs Phil Wood, etc.
