From shifting stress, always the middle ring. Granted, much of this is on entry level bikes used as rentals where the user is typically not very skilled with shifting, but I've seen it on customer bikes too and still see it as a weak design...and a bit silly since the tiny bit of "extra" weight matters little on a 30+ lb bike. I'd rather see a 5-bolt spec for less fleet maintenance and happier customers.
