A great 130mm chainring at a great price!  We found a little stash of 130mm Shimano DuraAce 52 chainrings.  It goes back a few years - its the 7402 model.  Probably great for 9 speed, not sure about 10.  

The ring is labled "A" which means it is designed to be paired with the appropriate Shimano 42 ring.  But our understanding is that the ring "compatibility" is not such a big deal - with a non-42 you will still get good shifting, but not as good as if you used the 39.  There are so many 130mm bolt circle cranks out there - this is a great way to freshen up the one you have with DuraAce quality at a 105 price.
