Stronglight Granfondo cranks

Hi,
I've got a set of Stronglight Granfondo cranks but I can't find anything about these online.
What I'd like to know is are they JIS?

Many thanks.

Not much help but I have a stronglight rockstrong which looks the same in triple and rockstrong century. The previous owner had sent me both cranks including a shimano JIS BB. Without thinking I assumed these were JIS. Both started to creek and eventually start to fall off. The previous owner must’ve installed them using a JIS when they are probably for ISO. Therefore damaging the crank, rendering them useless.
Anyway check this link: https://velobase.com/ViewComponent.aspx?ID=C311B07D-028A-46F4-B77F-614390B87D02&Enum=115&AbsPos=41 Ironlight looks like yours and marked ISO.

Thanks. That's actually very helpful. I'm hoping that the previous owner used the correct version. Maybe a Campag bb at 111mm would work. Incredible big lack of info from Stronglight as well. I'll have to look for an older catalogue. 1998? Hopefully there will be something out there.

post a link up on here if you find any from the 90’s, I only found early 80’s and the 2001 cat on disraeli gears

If I find anything I'll put it up here.
It's taking time.
