Hippy, it looks as though you're the winner here, they're 170mm.
What chainring do you want?
I have 42, 45/46 (can't remember which), 48 and (Ithink) 50 teeth.
All in pretty good nick.
You can have it with all four chainrings for £55 if you want.
How do I get in touch with you? If you're in London you might find it easier to swing by my work and pick it up.
