Too bad you don't need 172.5; I have one that I need to get rid of and haven't felt like doing the ebay shuffle.

Double or triple. I have a 9 speed ultegra double octalink lying around. 170mm. I think I still have a bb to. Its used, but still funtional. Let me know if you are intersted.

Yes, its a 39/53. If you cover shipping and a 6 pack, its yours.
