How do you explain cyclo-cross bikes then?
You have one frame crack and assume it's down to using it on tracks. What if you had a frame crack whilst cycling on the road? Where would your assumption take you then. n=1 is not a big enough sample set to draw any conclusions.
I dont assume anything skwerl....

A via nirone and a cyclocross are two completely different animals. A cycocross is deliberately made to take punishment...a nirone definately isnt, (otherwise it's be marketed as a cyclocross bike).
I made the point about the frame because most of us pick up an assembled bike. It feels solid. Pick up a bare frame.....you soon realise how heavy all the components are, that's what gives it its solid feel.
It genuinely surprised me how light the tubing was.
The LBS were (hopefully) genuinely surprised the frame had gone...the first Nirone they'd seen do that.
I'm not a big guy, 10.5 to 11 stone, so it's not me that killed it.
Its been a purely summer bike until this last winter, so it's not really been exposed to corrosive elements.
Of course, it could have been a poor weld, but i woudnt have thought it likely with todays high tech welding and manufacturing processes.
I do like to honk up hills...that puts a lot of stresses through the bars and through the cranks...perhaps thats a factor.
What i do know is, although as stated i dont do it that often, i'm not averse to going onto tracks....something i would guess most road bike users dont do. It's reasonable to assume this
could have been a factor.
