chain guards?
Anyone make/sell these anymore? I've seen some on newer, handmade bikes, but I'm wondering if there are generally any for sale somewhere?
thanks

Well, this one's beautiful, if obscure.

I plan to put one on a commuting bike I'll be building next year. If you're talking about the guards that protect the spokes from the chain and derailleur on the back wheel, I just bought an old Huret on ebay. I'll just bet there's lots of cool 'over the chain' chainguards there, too!

Cool. That's a nice one. You know if that's sold/distributed in the US, and if so, how much?
I was kind of looking for something like what Rivendell has on it's Quickbeams that covers the entire chainwheel, maybe keeps dirt off the chain, as well.
Here it is:

Anyone know if one can get something like this anywhere? Sheldon Brown refers to it as a "chainwheel disc."

Wallingford Bicycle Parts used to have Sogreni parts on their site, but they are not there any more. It's very expensive designer stuff.

You're not going to like my post . . . 
It's a piece of 16 guage aluminum - rough size: 10 x 10 inches.
I locate the center and fix it with a center punch.
Scribe a set of circles inner, outer and bolt circle,
then start cutting. Takes about three hours.
(I want to be careful - cannot add the metal, once cut)
I like this 'cause, being a roadie, I never use a front derailleur,
and it presents a clean looking seat tube.
When one down shifts, the chain "crawls" up to a larger cog.
When one up shifts, the chain "drops" to a smaller cog; the
resulting loop, like whipping a length of rope or a garden hose,
travels down the chain causing derailing to the outside.
You can see similar plates on tandems. They are similar to
a rock-ring used by mountain bikers, but the size is too small
to cover a 52 tooth chainring.
