View Full Version : converting free wheel to fixed?

Its really hard to find anything about this since most articles on converting bikes usually just deal with multigear bikes to ss/fixed. I'm just wondering how I'd go about converting my single speed to a fixed gear. Can I just take apart my freewheel mechanism? Or do I have to drop money on a fixed hub? Thanks.

Cog, bb lockring, rotafix, loctite.

While I don't really have too much of any idea of how to physically do this, atleast it looks it like it will be cheap.

What he said...
1)Buy a cog to thread onto your freewheel hub
2)Thread on a bottom bracket lockring onto the hub
3)Rotafix the cog to the tightest
4)Use red Loctite to hold the lockring and cog in place
They are called suicide hubs, look it up on Sheldon's site or do a search on here.

Getting a new set of wheels with fixed gear receptacle(s) is probably a better idea. For one, you are going to feel safer thus more enjoyable. And, if so you choose, you can keep that wheel set for a new fixed gear bike. This way, you don't need to ruin your single-speed wheels for later use. Some people go back to single speed and a lot of people like having both FG / SS as options, anyway. ... Pay upfront, work less, worry less, more fun. Good for me.

are you sure your hub isn't a flip-flop, which is capable of holding a cog and lockring on its other side?

no, I'm actually not sure. How would I identify that?

Is your hub like this?

Check if the hub's threading is "stepped down", meaning it has two sections; one larger than the other.

Where did you get your bike from, or what bike is it, etc?
Does it have threading on both sides of the hub?

check the other side of your hub to see if it's threaded. If the threading on the other side of the hub is "stepped" as vixtor says, it should be able to accept a cog and a lockring to run it fixed. In that case, just remove the wheel, add cog and lockring to that side, and you'll be running fixed
