etype BB question

I'm looking at a BB mounted Blackspire Stinger and reading the install instructions I know I need an etype BB.
Current BB is a Shimano BB-ES25, Octalink spline, 68mm x 118mm
Looking at CRC etc and on the Madison site there's no Octalink etype octalink BB in a 68mm x 118mm size. The only one on the Madison site is 68mm x 113mm
Does this then mean I'd need to go for completely new cranks with a different BB type to accomodate the Stinger???
