2 Quick Conversion Questions
1. Do you need to use spacers when converting a ten speed to a single? I figure just removing the derailer and shortening the chain will work and use a chain ring on your 8/9/10 speed cassete am I wrong?
2. Can I use a quick release skewer with a single speed or fixie?

1.) It depends on your hub, spacers or a bmx freewheel will work, depending on the type.
2.) Yes.

Quick-Release or Nutted?
Track hubs generally come with solid axles and track nuts. This is because most velodromes have rules requiring this type of wheel attachment.
As a result, it is widely believed that quick-release axles are not suitable for fixed-gear use. This is false!
It is my belief that the velodrome rule dates back to long before the invention of the quick-release, when the choices were standard nuts or wing nuts. The protruding "wings" of wing nuts might constitute a hazard in a crash, and I believe that's why the rule was instituted. Since quick-release skewers don't have any sharp projections, that becomes a non-issue in practice.
If you are going to use a quick release with a fixed gear, you should make sure to use a good quality enclosed-cam skewer.

1. Depending on what gearing you want you may not have the straightest chainline but as long as you aren't running your chain from your big chainring to your biggest cog the only problem will be noise. (this method requires you to leave the whole cassette on the bike (the gears you aren't using are your spaces)
2. QR is fine with singlespeed. Possibly fine with fixed (i've seen it done but not by me so YMMV). Your only problem with QR will be chain tension but it's not impossible to get good tension with a QR

Besides, if you have it in the back you probably also have QR up front, and who wants to bother locking both wheels all the time (unless you're in a particularly high crime area where you'd want to do this regardless)?

I have a QR on my fixed MTB. Works for me, and I doubt a street geared fixie will generate more torque than a 32/20 geared MTB with a big guy mashing up a 60* hill

If you want to have a QR on a fixie or track bike without converting the hub, you can always install a cam device that threads onto the axle instead of the nut. These install on each side of the hub by simply threading them on instead of the nut. This is a much cheaper and simpler option as it does not require any hub alteration.
