Fixed Gear Conversion

I am currently involved in rejuvinating an older Fuji back to it's once proud condition. Once that is finished, I am going to start dismantling my current roadie with the intent of converting it to a fixed gear.

The way that I'm thinking it will go is that I will remove the casette from the rear wheel and attempt to disable the freewheel quality using some method as yet not discovered by me. Then I'll attempt to attach the only rear sprocket that the bike will know for the rest of it's life. I have seen some stuff about lockrings but don't think I fully understand the importance or the complications that almost certainly are before me.

What implications does this method have? Should I just shell out the 25bucks for a flip-flop hub or fixed hub and build a wheel around that? I'm pretty well-versed with tooling and mechanical methods so I was going to just jump into it and figure out the problems as they are presented to me. Thought I'd get some experienced feedback though. Thanks alot in advance and any advice is much appreciated.

how old is your road Bike? Are you sure it has a casette and not a freewheel? If it is a freewheel as on most older bikes you can make a suicide hub pretty easily with a track cog, spacers and a bottom-bracket lock-ring. Use the extra strong locktite on all parts, and I would recommend a brake. Suicide hubs can come unscrewedby back pedaling really hard or track stops(thats why they call em suicide hubs) . You are better off getting a flip-flop hub from nashbar for $35, but then you need to get new spokes if your flang size changes and possibly new rims unless yours are 32 hole. You can get prebuilt cheepy track wheels on ebay for about $100

Yes. There may be a way to disable a freehub. Like pouring sand into it. But really, when you read your description of how you're planning on making a rear wheel that you will at least partially depend on to stop, does your idea sound like a good one? I am the world's cheapest [email protected], and I would not do that.

In fact, if I were you, I'd shell out the $50 and get a built fixed wheel. I built my set of fixed wheels, and have pretty much regretted the extra $150 ever since.

This is a waste of time. Go buy a real track hub already. They're not expensive. Or you can reverse engineer the surly fixxer. Think you can do it for less than they sell it for, or less than a track hub costs?
