Re:
I have a couple of options, both 170mm.
A Race Triple. NOS chainrings, but not cranks.
A Comp Triple. I'll have to check the condition on this, but it is NOS or very near (I had two and can't remember which one I've still got).
Looking for £70 for the Race or £100 for the Comp (once condition confirmed).
I can check them and get photos tomorrow if interested.
