Derailler Hanger - Jamis Capri - can't remove stud

Have a Jamis Capri - probably about 4 or 5 years old. Wanted to change the rear derailler. The existing derailler mounts onto what seems to be a derailler hanger, but not by bolting on. Instead there is a stud that is mounted on the derailler hanger, and the derailler slides onto that stud and is held in place wiht a small c-clip.

I've got the derailler off, but can't figure out 1) how to remove the stud (it just spins when I try to unscrew it, and 2) if I do get it off I"m not sure the hole it's mounted on is threaded, therefore nto sure I can mount the new derailler.

Any ideas on how to remove this stud, and do I need a new derailler hanger if I do manage to get it off anyway?

Hi billy, I am not familiar wihtt he Jamis Capri but I think it might be a lowend model. does the hanger mount on the dropout with the wheel? if so the derailleur is likely swedged to that hanger and you will need a new one. why are you changing the derailleur? is it broken?

So how did you end up removing it from the bike? Wasn't it just a matter of unscrewing the pivot bolt with a 5mm hex wrench? Maybe a pic will clarify the issue that you're having.

Definitely need a pic; that description leaves me puzzled.

some hangers are held on with a chainring bolt, use a chainring nut wrench to hold the back

bikepedia shows the 2005 Capri 2.0 and 2.4 models are spec'd with a Tourney TX30 rd (with attached hanger).



OP, what derailleur did you choose as a replacement? I know little about the Tourney rd, but I suspect your options are very limited.

OK...I"ll have to go down to the garage to get all the specifics, but Bianchigirl, yo'ure correct, it mounts on the dropout.

The person who described it as swaged might be correct too -- there was a small soft metal collar holding the stud firmly in place. I removed the collar (maybe a mistake) and now the stud spins freely in the hole it occupys in the hanger, but it still won't come out. At this point I think I may have backed myself into needing a new hanger that will solve my problem - since I suspect if I get the stud out, that the hole it mounts in is not threaded and won't accept a new derailler.

The orginal shifters on this were some low-end SRAM twist grip shifters, and they weren't working well. My daughter couldn't shift the things. I took it apart, greased it, tried to make it easier for her to work -- and it basically was just worn out I think. I couldn't really find a replacement, but found a cheap deal on a SRAM derailler that was a bit better (SRAM SX4) and a shifter to match it.

I hate bikes sometimes.

I ran into this recently with a Japanese frame with horizontal drop-outs. I removed the c-clip that holds the
old derailleur like you then prepared the new derailleur (105 long-cage) by removing the threaded stud and internals...leaving a hole and a spring. I greased then slipped the new derailleur with spring onto the old hanger
and applied the original c-clip. Many km's later it still works fine.
