That's very interesting. I have heard of at least one reference to the use of 6mm (.236") balls in Stronglight bb's, and if so that might allow one add'l ball???
How many of the 1/4" balls fit now? IIR there should be 11, and I've taken apart a few factory builds. Also, iir, The late Sheldon's site made note of a rolling diameter (ball track diameter) discrepancy with respect to using non-Stronglight cups or spindles with mating Stronglight parts. This might explain clearance differences regardless of ball size.
Anyone have details on this?
Sorry, I don't have a loose Stronglight bb here to look at.
