tracknicko – ideally medium cage, but long would do. Or possibly a whole mech. iain.wallaceATgmail.com if anyone can help out.
My rant is more the relative cost of spares to the new price. The complete mechs are always discounted, whereas the spares aren't. So the spares cost as much as the mech (nearly). I'd far rather* repair my X0 than buy a new X9, yet it's the more expensive option.
*performance wise they're probably the same, more for reasons of avoiding unnecessary waste etc.
Cheers for that ebay link, i'll look into it.
