    Removing Fixed cog from flip flop hub

    New to this forum but not the forum world. I did a search and didnt exactly come up with what I was after. I have a single speed road bike with a flip flop hub. Fixed cog on one side and freewheel on the other. I dont ever use the fixed cog and would like to eliminate it all together. Is this possible using the existing hub or would I have to change out a bunch of parts to do it? I only want the freewheel. Please chime in and give me your thoughts. Thanks

    If your bike isnt getting dirty, then you arent doing it right.

    You can take it off with a chain whip and lockring tool, but the weight savings is so minimal that its not worth it.

    Well it is worth it if you are never going to use it and it is just going to sit there collecting road grime build-up until it corrodes.

    Lockring tool and chain whip yes. If you want to go barbarian style, knock the lockring off with a hammer and screwdriver and then remove the cog rotafix style.

    This is right up there with removing the dork disc with a blow torch method.

    in one case, i broke a Park and a Nashbar chainwhip on a stubborn cog.

    used a nylon mallet and a scrap of wood. would not use metal on metal.

    Once you get the fixed cog off, you can thread another freewheel of a different size onto the stepped side of the hub. Yeah, not much thread there, but enough to hold the freewheel. And you don't need the lock ring. Just make sure the chain is long (or short) enough to work with both cogs. Now you've got a double-speed!

    The tiny bolts that secure the chain to the handle of the Park chainwhip suck. After breaking and replacing mine about ten times, I reattached the chain using a KMC master link and haven't broken it since.

    Those bolts are about as useful as an ice cube in -5 f weather.
    Strike like an eagle and sacrifice the dove.
