Where can i get one from, think chain is a 530 of a fireblade

I used to use `supersprox` - can't find a direct link , but I allways found them to be very reliable and reasonably priced .

B&C Express can supply renthal alloy sprocket blanks to your spec, I have had a few supplied by them over the last couple of years & the service was great.
