Hi,
My wife had completely worn out her 2011 Rockhopper SL Comp drivetrain. I've ordered a new cassette and chain but have decided to replace the entire crankset rather than order 3 new chainrings.
The current BB is a Shimano BB-ES25 octalink 68x118.
I've messed with everything many times but ever a BB so I'm trying to learn about compatibility.
Here is the bike: http://www.specialized.com/au/en-au/bikes/archive/2011/rockhopper/rhintrockhoppercomp#specs
From what I gather, I can fit any GXP or Shimano 3x9 crankset as a replacement into this frame? Eg. http://www.chainreactioncycles.com/Mobile/MobileModels.aspx?ModelID=75695

Thanks for any help and advice
