Yes, I've read through Jon's web site.

But one of the reasons I was asking the question is because,
my LBS just swapped over from double to a triple SR Apex crankset
on my Motobecane Super Mirage, no problem. Took him just minutes,
I watched him do it.

The spindle and bb are not original though, could have
had a longer spinal replaced already.

I know the bikes are different, that's why I was asking.
