Query about Stronglight BB

I think (I have read on the internet) that stronglight 80/100 are JIS taper. and need quite a long spindle.

I was looking at them to use a ridiculously long titanium BB that I have sitting around.

My hunch is to go for 118mm.

I'm surprised spa cycles didn't know for sure - they are the stringlight kings.

If it would be suitable for my bike, I might be interested in buying it from you.

Spa Cycles told me that I could use ISO or JIS, but even they were uncertain as to what size I would need.

Thank you for taking the trouble to respond so promptly.
