Re:
They're nothing spevial, I mean, they look funky, if you like that sort of thing, but they're nothing special to ridethink I sold my full bike (which had been upgraded and refurbished) for around £100 a couple of years ago, so the ask8ng price for that "NOS" frame is frankly ridiculous. It may be NOS, but it's still a Kirk!!
As for the frames breaking, they did, but mine didn't, anyway, you see plenty of high end aluminium frames that crack, so I wouldn't be unduly worried about that.
