Anyone know where I might find a dura ace 7803 middle 39T chainring?

Thanks, I've searched there and nothing other than some complete 7803 crank sets. I get results from the US and UK but nothing from other parts of the world. Are there other sites for such items in other jurisdictions?0

just change the country designation at the end - eg. ebay.it or fr or what not.
The camera down the willy isn't anything like as bad as it sounds.

Thanks and yes I've tried the part number, it's Y-1G598130 but no joy after some hard ebay searching. Other shimano generations don't fit. Some have thought 5803 which I think is 105 would be the same - but it's not, not even slightly! I could buy an entire crankset from the US for about $400! Or just upgrade to the latest ultegra but this dura ace g'set looks right on the corresponding age frame. It's also really really good.0

Not Shimano, but I think either of these would work.

The inner BCD is different though, 74mm rather than 92mm, but you could change the inner ring as well at the same time.0
