Been waiting for this post since you responded to my thread. They look just like what I need for my road bike. I was waiting for the thumbs up so now I can order mine. Thanks Nigel.

Ordered one of these chainring guards from this vendor for a 50 tooth 130 BCD crankset and it came in sooner than expected. I got it just a few days before my MS 150 ride and installed them on my road bike this past Friday morning. They fit perfect and work really great. No more grease on my legs or getting stabbed by the teeth on the outer chainring when the chain is on another ring. They are also very light, which I was somewhat concerned about their weight. Thanks for posting the link to the vendor on eBay.

Oh! I forgot to mention, it was a breeze to install. Took about 15 minutes.

What tools do I need to install this chain guard. I don't have many so I would probably have to factor the purchase price of the tools into the total price. I guess you have to remove the pedal and I think that requires a special tool.
All you need is a hex key (allen) wrench and maybe a large flat head screwdriver to hold the back lug in place while you turn the forward one. You don't need to remove the pedals. Just make sure that you align the notches on the chainring and the notch on the guard with the pin on the crankarm when you put everything back together.

When you remove all the ring bolts, the outer chainring will come off. If you have a triple crankset, you may have to loosen the ring bolts between the small and middle ring. I had to do that on my wife's Truvitive crankset. The Tiagra that I put them on did not require anything else being loosened or removed.

Even better is one of these:

I've always called it a chain ring bolt spanner.

Heck of a nice price for that tool, especially with free shipping. A good addition to your bike toolbox if you worked with chainrings all the time.

Will this chainring guard work on a triple? Can I leave the outter chainring in place and still use the guard? Does it come with longer screws and or spacers to keep it away from the outer chainring?
