I have NC29 ally race 520 sprockets in stock from 39 - 43T - must have 50 plus - some good used as well.

Plus quite a few in 520 hard anodized ally - gold finish - but these are mostly on a 3 week order time.

I'm with Wozza on this one with some big washers aswell if thats the sprocket you want.But what size are the holes between the mounting holes there is also the Renthal Twin Ring.

You could goto http://www.powerlinks.co.uk/sprockets.html" onclick="window.open(this.href);return false;

They will make you anything any size you want in alloy if you want 525 then sort out your own proper hard anodizing as they can't do the proper Hard Anodize.(trust me I've been through this with them before)
But it would make more scene on the money side to buy a few 520's off the shelf.
