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)

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

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.

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.
