I have a 2007 rockhopper disc with original octal ink crank...bottom bracket is now needing replacing but have found online a contradiction in correct spec.....some say 128,118 and 113 by 68mm for the shimano es 25...do you know which is the exactly right one?...also my rear cassette needs replacing...as long as it is a 9speed cassette does it matter if it's a SRAM or shimano??? Many thanks Dave

    This is correct as it is crank specific measure what you have no or heck on Speshs webby as they have the info there. Presuming the cranks at original.
