Yeah... no XTR here. Each crank says Shimano and that's it. There's no other text anywhere on the crank/BB area. SO I take it I'm using V2... good to know for the future, I guess.

Just for the sake of knowing... my bike is normally noted as "amazing frame with average components." Okay, got that. Can someone link me to a bike parts web site a Hollowtech crank that would in some way shape or form compare to the Octalink crankset I have? Just for sake of comparing and knowing prices for the future if indeed I DO ever switch it out...

And, not to hark but, can ANY mountain bike take ANY kind of BB? Or is there a specific kind of bottom frame hub that I must have to fit into certain BB's?
