Ok, well maybe I was lucky.
I'm cool with the 9-balls, too. And I prefer loose balls in BBs rather than cages - in an install like this it removes a constraint, that the cage has to fit between the spindle and the cup.
Ok, Zand, that's all cool, and I'm glad for you that something worked pretty quickly. But what IS a 5s-B? What company makes them? Are they in Sutherland's or some other handbook?
My other thought if my Shimano hadn't worked was to measure the old Peug spindle and try to match it up in Sutherland's to a close-matching cotterless spindle.
