Fonseca, others. Has anyone re riveted a R-Derailler? (4 posts)
|  Fonseca, others. Has anyone re riveted a R-Derailler? | Mr Magoo
Jan 6, 2004 6:58 AM | | This was suggested on my SRAM post which is way down the page by now.
In my box of broken parts, I now have the potential to merge 2 broken SRAM 9.0 rear deraillers by replacing the snapped off first knuckle with a good knuckle from a unit that snapped at the long cage pivot. Or vice versa, I guess. Has anyone bothered to try this? I can see drilling out the rivets to remove the broken component, but reassembly must require a more sophisticated ricet than what is found in my pop rivet kit. (Which was very effective on aluminum gutters) I can see reassembling too tight or too loose. Aren't these things designed to accept lube? While I like recycling, this is a $50 part; is this process too labor/pain in the butt intensive to justify the effort? If so, why am I keeping a box of broken parts? Thanks a million for your valuable input.

Jan 7, 2004 1:32 PM | | I can't really answer your question, although I'm curious as to an answer too as I have a 9.0 and a 9.0sl, each broken, but it did cause me to think...if it's already been stressed enough to break, could there have been enough fatigue in the left over pieces to cause them to break that much easier... I too have often wondered why I keep a box of broken/spare parts that never seem to get used...could make an interesting collage for the wall... |

I have never broken a knuckle believe it or not--despite years of bending derailleur hangers--so I haven't done it myself, but when a riding buddy of mine ordered a replacement al knuckle for his, he just popped off the C-clips and it was easy.
Edit: Hmm, actually I think you are out of luck. I just looked at the only 9.0 derailleur I own, and it does indeed have rivets, all my other Sram derailleurs have C-clips. I honestly don't know if the pins and clips will work on 9.0 or not, although I'd bet they would. Maybe you should give Sram a call.
