From middleburns web:
Having the right BB length is crucial to having gears that work as well as intended.Middleburn cranks run a 50mm chain line.
For a standard MTB setup a 113mm axle is needed for ISIS or square taper.
However, there are far too many variables to always be able to predict what bottom bracket you need. BB-mount ("E-type") front derailleur and chain devices can throw a stick in the works, as can a lot of oddly designed frames.
If in doubt have your local bike shop fit your cranks.
So 73/113??? If you already have the bb, why not try it and see?
