Stronglight 80 crank tapers
Stronglight 80 crank tapers
Have picked up the above crank. Can't remember, from my last ownership of one, if they are JIS or ISO? I know older Stronglights are ISO butnot sure where the 80 stands in the way of things.

VeloBase has ISO:

My point exactly!

FWIW
My understanding is that the Japanese adopted the French taper when they set their standards.
So,
Stronglight=French=JIS

Re: Stronglight 80 crank tapers
Is the angle of the taper any different between JIS and ISO? Or is it just the length? If the angle is the same then you could just try them on whatever BB you have to hand, checking to see whether the bolt bottoms out on the spindle/not enough of the crank is supported by the spindle. No doubt Brucey has advised on this topic in the past for those good with the search function.
