Interestingly enough, I decided to do a side-by-side comparison of the old Acera and the new Deore. I'll be damned but it appears that the Deore cage moves out even further than the Acera, which would make no sense whatsoever.

This is certainly bugging the heck out of me. As of now, I'm riding around without the FD, with the chain in the large sprocket. So far the chain hasn't fallen-off and seems pretty stable. Before I was riding around with the new Deore, but with only the use of the small and intermediate sprocket, otherwise kicking into the large sprocket and riding would have likely damaged the cage and/or chain over time.

I took a look at the product insert/manual that came with the Deore FD and a little compatibility chart specifically stated it should be compatible with the MC19 crank. I'm fairly certain my BB is the 111 Chinhaur Doctor Morbius found stock on his M60, although I have yet to verify this.
