Is my Chorus Derailleur bent?(7 posts)

Is my Chorus Derailleur bent?DY
Jan 12, 2002 4:13 PM
I just purchased a new 9 speed Chorus rear derailleur and installed it. It works fine and I can hit every shift fine. I was looking at it compared to my friend's Shimano and I noticed that the bottom wheel/gear is inset and it looks like the cage is bent (see photo). I am asking because I have no experience with these derailleurs and thought someone might know. Maybe this is normal for this product. Thanks. Dave

Take it to a good shop and have them check the alignment of the derailleur mount. There is a special tool made to bolt in place of the derailleur for this purpose. Have them look at your new derailleur also. It's highly unlikely that it's bent.

From the photo it really doesn't look like a hanger issue. Usually, hangers bend to the inside, and this one would have to have bent out- I'm not sure how that would happen.

It appears that the cage itself is bent- but it could be an optical illusion. I agree that the hanger should be checked, but I put my money on the derailluer itself.

Yes it is a new frame build. Brand new frame, brand new Chorus 9 group. Wierd thing is that the top wheel/cog looks straight and true, but there is a real curve that can be seen in the plates that hold the bottom cog, so it is off at an angle. Oh well, I am confused.....I guess I'm off to the bike shop tomorrow.....again.

I just checked my rear der again and it's quite "straight" all the way across the cassette.

My guess would be the hanger isn't right but then again your comments about the der alignment seem to indicate the der might be "goofed". ???

Let us know how it all turns out and good luck.

BTW: Why did you build a bike with C9 instead of C10???

It sure looks like a bent cage to me!Rusty McNasty

Did you spill the bike? Catch a branch between the spokes? Catch the derailleur on something while storing the bike? Maybe the wrench-monkeys at the LBS bent it?
Whatever the reason, that cage is bent!
