54t Sprocket diameter?

[BMH]

I don't have one on hand to measure and I seem to find diameters ranging from 6.5" to 8.75". So does anyone know the outer diameter (addendum) of a 54t sprocket?

Our 52tooth sprocket has an OD of 10.71" so I'd imagine a 54tooth has a OD of about 10.75 - 11" or so.

520 chain mind you...

A 520 Chain has a pitch of 5/8", so, the pitch x #teeth divided by Pi, gives you the pitch diameter. (where the centers of the chain rollers lie), Sum half a pitch to that, and you have the overall outside diameter at the teeth tips
