Octalinks go up to super wide in MTB groups, I have a 121mm BB-ES51 in the parts bin. Can't remember exactly how it works, but bear in mind that there are two kinds of Octalink, with different spline lengths. Make sure you know exactly what you're doing if you're toying with the idea of using a BB that doesn't exactly belong with your cranks.
V1 and V2? I know i need a v1 with the shorter spline so i will bare that in mind
