Wanted: 50T Chainring 1/2 x 1/8; 130 BCD!

Dear community,

I am in need of a 50T 1/2 x 1/8" (would also take 49 to 53) chainring for my sweet 130mm BDC Dura Ace crankset! Alloy would be nice but is not essential.

Can someone offer me a decent one, used - or even better new?

I live in Austria, so shipping would be great. A friend of mine visits London on a regular basis, so meeting him or sending it to his adress would be a possibility too.

Thank you lots in advantage, cheers

Frederik

I've got a 130BCD 52T TA Alize 1/8" track specific chainring that I bought from Condor for about £60 a couple of years ago. I have no used for it now. It is in very good condition and I'd be happy to post. PM if you are interested. I think I'm looking for about £20 for it.

This is the actual ring: http://i1103.photobucket.com/albums/g463/stonehedge1/IMG_6756640x480.jpg
