I have a rear wheel that's been living in my closet for the pass 6 months and I want to convert the Shimano freehub to a singlespeed. There's a deal on nashbar.com for a singlespeed convertion kit, but I already have a 18T cog I got from a Gusset Singlespeed conversion kit that I want to use for the new rear wheel. I already have a 11T SRAM lockring. I just need cog spacers.

So where can I find cheap deals online for just cogs spacers? I'm talking <$5

- take apart an old cassette you have lying around
- PVC pipe + hacksaw at your LHS

There was a guy who sold them through the mtbr.com classifieds for a few bucks. Misfit psycles has them too, but probably more than 5 bucks, and they're in Canada.

Try loose screws

bottom bracket spacers will work for this.

go to your LBS and ask if they have any laying around. they often do. i got 8 for a few dollars.

use a bb lockring.

depending on just how far he needs to space it out, that's a good idea. usually, though, a bottom bracket lock ring will be too thick. definitely worth a shot, though.
