Well, for the past two nights, I have been researching on how to convert my 12 speed road bike to a fixed gear. I think I give you guys a summary. Could you guys tell me if this is right and I should follow through with this. Well, I should buy a new crank, remove the cassette and shifting ****, buy a cog,buy a new chain, buy a lock ring,buy spacers put all that **** on, then keep the brakes. I have a fixed gear... I have heard that I need a new rear tire, but I have seen people convert mountain bikes/bmx bikes with singlespeed. by the way, I have vertical dropouts.
