Has anyone done a Rivendell Quickbeam SS to fixed conversion?
Rivendell says I don't need a BB lockring, but others have indicated that I should. Any comments/observations to share?

Bottom bracket or hub? Or do you mean a bottom bracket lockring on your freewheel hub?
If it's the latter, I'm inclined to say yes. It won't actually prevent your cog from threading off as a number of folks here can personally attest to, but it may take longer before that happens. Add some blue loctite for a little extra security.
On the other hand, if you have a Quickbeam you probably have a better bike budget than a lot of folks. I'd build up a new wheel with a proper track hub.

Word. Bostontrevor pretty much nailed it. Rivendell only says what they say because they provide the bike with two cantilever brakes, and they assume that you'll use them. To get the full flavor of fixed riding you will need to learn a lot of backpedaling and backpressure techniques.
If you want to make a real go at riding fixed, just get a new back wheel with a proper track hub.

And for a proper hub, let me recommend a Kogswell 120mm rear hub. They're fixed/fixed, so you can use any combination of track cog or freewheel. And they're derived from downhill mountain bike hubs, which means that they're rated for extreme duty.
