What is the BCD?

Hello, you have everything else except the BCD for this item. So, what is the BCD for this chain guard?
Hi there,

The BCD of this chain guard is approximately 130mm.

Will this bolt onto a Dura Ace 7800 Crankset?

Will this chain guard (and the chainring) bolt onto a 7800 crankset? The Alfine is only available up to 170mm length, (I prefer 175) and I happen to have a spare 7800 crank in 175 crank sitting around which I'd like to use with this single speed bike... Also, chain-alignment? Will this require spacers or adapters?
This should bolt on no problem, we would need to test fit to check chainline etc.
