I'm thinking of going 1x9 with my m952 crank.

I would like to have a new and longer bb to "center" my bb and have better crank arm clearance.

Can i replace my current bb and use the new xt or xtr bottom bracket (hollow tech II)?

My frame has a 68mm bb shell.

My plan is to keep the crankarms and rings, fit a new BB and run a chain retainer (mrp 1.x)

My concern is that my crankarms and rings will be not compatible with the new BB.

Also in the future, i plan to upgrade the 32t ring to a new 36t ring. Can they all work together?

Sorry to bump this old thread, but I'm having a really hard time figuring out what I need.

I've got an XTR BB that is 112.5mm wide. I need to go wider. I'll probably jump right to the 118.5 Road bottom bracket. Which one(s) will work? How do I know what BB's accommodate and Octalink V1? A link, or part numbers would be hugely helpful.
