    Newbie question about converting a road bike to fixed

    Hi, I am mad keen to get an old Peugeot frame I have made into a fixed gear bike. I had a few questions about the hubs. I have a working road bike that I can take parts off but will I need a new hub for the back wheel or can I use the one already there somehow.

    "mad keen"

    Awesome.
    Really, I need to use that sometime. In real life, not just on the internet.
    In fact, I'm taking that out of context and making it my "signature," or whatever.

    The problem with the hub you have is that it is not set up for a lockring. If you imagine a jar of peanut butter viewed from the top, the lid is your cog, viewed from the drive side; tightening the lid is pedalling forwards; and rotating the jar clockwise while holding on to the lid is resisting. Notice that when you "resist", your "cog" has a tendency to unscrew. A lockring prevents this from happening and what makes a hub fixed specific is provisions for a lockring.

    You can do some ghetto **** with loctite or jbweld to keep this from happening with your current hub, or you can just get a real fixed hub. I'd just get a fixed hub, they're cheap.

    Thank for help, I was looking up hubs on the net, not very common this side of the water. I will have a better look later.

    it is probably a better idea just to get a new wheel.

    Would a pickle jar work better for a fixie? What about a jar of Mayo?

    If the rear wheel is a free wheel then you can just redish the wheel and spin a cog on. No need for a lock ring, just make sure you use a front brake! To set a cog you can rotafix it or just climb real hard up a big hill.

    If the rear wheel is a cassette type hub then you will need a new hub and at that rate you may as well get a new wheel.
