My esteemed mother has a story about once having to reassemble a disintegrated freewheel (including collecting the balls from a fair area of gravel, although you can run a freewheel without balls in in a pinch; it will graunch a bit when you coast, but work fine when you push...) half way up the Stelvio. And still beating a soon-to-be first-cat roadman to the top, of course.
Wow! Cool mother!
I want to know who the roadman was ;-)
Forgotten his name; it was a 15 years or so back. And he was suffering from stomach problems and inappropriate gearing, I think...
