This was kind of a strange one - most of the components showed signs of pretty bad corrosion, but the frame itself ended up being very clean.

That said, I don't think the old Exage Mountain Derailleurs will be worth cleaning up - they show some pretty deep rust pitting, and the main springs are really rusted inside.

This is just like the one that was on the bike:

I believe it's a bottom pull (no cables route on the top tube at all) with a 28.6 clamp diameter. Is there a good XT equivalent or should I stick with Exage Mountain?
Thanks!
