Subject: RE: Bending back a bent rear derailleur hanger acumenjay - 2009-07-29 7:33 PM
Hey all, I have a question for you mechanics or anyone who has gone through this (I'm assuming it is common).I went down on the bike this weekend and went into a slide on the right side of my bike doing some damage to the shifters, handlebars, front derailleur, pedal and most of all (or so it appears to my novice eye), the rear derailleur and hanger.I've moved back the front derailleur and shifters and the handlebars/shifters/pedal all seems to be cosmetic mostly.Now, the rear derailleur hanger is a little bent and I found this article:http://www.parktool.com/repair/readhowto.asp?id=39I'm curious, how many of you have attempted this on your own and what is your experience level? Also, would a LBS be inclined to attempt this repair or not. I'm not sure if they would be a little risk averse and not want to risk breaking the hanger on you or not....What do you all think? I'm hoping this is not beyond repair...
Take it to a shop. It depends on who badly it is bent as to whether or not the shop will be willing to fix it.
If it's a replaceable hanger, you can get it straightened, but know that once it has been bent, it will bend easier in the future. It's best just to replace it if it is replaceable. Buy two and keep one on hand because they are very easy to replace and the derailleur should not require any readjustment if it was adjusted correctly prior to bending the hanger.
