Nexus chainring

stefano

Hi I have a commuting bike with Nexus Shimano 3 speed hub. I want to change chainring. What chainring shall I buy? I cannot find much info online.
Any idea what is the BCD?
What shall I buy?

the hub details will not help choose the correct chainring

you can count the teeth on the existing chainring, also how many bolts

if you measure the distance between two adjacent bolts you can tell what the bcd is...

Hi Thanks,
I had a further look at Shimano Nexus chainrings and they appear liker fixed to the crankarm:

Is it the case that I have to buy the complete Nexus crankset, including the chainring?
I cannot find anywhere separate chainrings for Nexus?
