Does anyone know the BCD of the Shimano XT FCM730 cranks offhand?

I can measure them later, but if anyone already knows that would be grand.

According to the Sheldon brown site, it's 74mm.

I need to replace the middle chainring is all and am unsure what to look out for. It's a 36 tooth ring at present. And I'd like to replace with like for like in terms of size.

Re:

There are two BCDs (Bolt Circle Diameter) on those cranks, 74mm is for the small "granny" ring, 110mm for the middle and outer rings.

Spa Cycles do some nice own brand rings that should do the job: http://www.spacycles.co.uk/products.php?plid=m2b0s210p0
