Octalink BB length for triple

[Youngtimer]

Hey, I just picked up a Blackspire badger triple crankset for my bike. Can someone confirm the correct octalink BB width I need for a triple to achieve a healthy chainline?

The BB shell is 68mm and I'm setting it up as 3x9

Depends on the crank itself and I don't know that crank.
The default for Octalink is 113 for 47.5 and 118 for 50mm.
You're doing 9 speed so either should be fine.
But not guaranteed as a few as always did odd things.

Thanks, that at least agrees with what I found online for shimano triples to match a 47.5mm chainline. Hopefully these blackspire cranks followed the same standard.

Will update with pictures soon

A look at adverts, this has the best picture of the instructions.
While the best length is hidden, it reads that longer is 118mm, so 113mm normal it must be.

Also if you know their website address, you can use the wayback archive to trawls the old website and hope it picked up what you need. The biggest pain is flash was used by many in the early 00s
