I just picked up a complete dura-ace 7700 9 spd group set for a good price with quite a few extras (couple seat posts, extra front-d, saddle, crankarm..) However The rear derailleur cage got bent while in his garage. And I was wondering if it would be possible to bend it back (my first plan), use it as is, get a replacement cage, etc. I think if Im careful I should be able to bend it back because its only a slight bend with no creases. Ive heard that the cages are pretty interchangeable on several models, but I cant seem to find replacements for any of them. Any ideas?
