Retiring a frame..
In the aircraft industry parts are lifed – Simplistically (I know it’s mroe complex than this) they know the likely duty cycle and numbe rof cycles to failure and they retire parts in good time.
They also monitor parts for cracks and know the crack growth rate so can tolerate cracks in flight structures for a bit before they need replacing. (In fact all parts have cracks in them anyway, they are just too small for us to detect using non destrucive testing, the crack monitoring just tells you when one of them grows big enough for us to find it).
So how does this relate to your question?
Ha ha (well I made myself laugh)
Ok maybe it does. The point is, you have got no idea what:
The design stresses are?
The duty cycle?
The predicted Life?
If any sub critical, or critical cracks are present?
And loads of other stuff.
This is no different from your state of knowledge about the frame when it was brand new. So I would just ride it till it breaks.Posted 5 years agowukfitMember
I’m looking at changing my frame, and am also undecided what to do with my old (2009) frame?Posted 5 years ago
It’s not worth enough for me to need to sell it, all I need is a cheap set of 140mm forks (or new ones for new frame) and I’d be able to build it up to a complete bike, which would affectively be its original spec….
But that’s having two very similar bikes, just one slightly better than the other,

Donate it to a local bike recycling group?
Better for it to continue a useful and happy life with a new owner than to lie alone and forgotten at the back of the shed.Posted 5 years ago
