I have managed to bend the rear derailleur on my gt palomar, the gear was not clicking through so I moved it through the gears set off and heard it crunch. The whole arm is bent.

It appears to be a shimano 7 sis dr of some kind. Can someone advise of the correct replacement I can buy. Would a shimano tourney or Altus be the right thing?

Many thanks for your help

  • The linked picture is a bit smallish for proper identification!

  • The picture is too small and out of focus. Jul 19, 2020 at 14:52
  • If it's that L-shaped arm that's bent, just bend it back straight. Jul 19, 2020 at 15:49
  • Ok added some other pics trying to keep below 2mb picture. Thanks again. I have tried bending the l bracket back but it is bent in two directions. Jul 20, 2020 at 9:11

As the picture shows the shifter, the derailleur is the bit at the other end, I presume its the shifter that has broken.

Any 7 speed shifter will work. this is a combined shifter so you will need a combined (with brake lever) shifter or you could choose to install a seperate shifter and brake lever.

You will almost certainly need (and be a lot easier) to get new brake and shifter inner cables to install the new levers. The cable installed though the shifter and brake lever then threads back to the derailleur or brakes. Reusing an old cable, is almost always an exercise in frustration followed by installing a new cable anyway. I would install new outers as well when doing a job like this just to be sure they are not a problem. Levers themselves are incredibly reliable, so its possible that the rear derailleur is part of the problem.

Brakes have two cable pull lengths, make sure the lever you purchase matches the brakes on the bike. In this case as the lever says V Brake so any V Brake compatible lever will work.

We don't do product recommendations, but something like ST-EF500-7R2A would be good. If cost is a consideration have a look to see if you have a local bike coop.

  • Hi no the link at the top goes to the dr picture. I uncluded the shifter in case that helped. When I added two pics it added one as a pic one as a link. If you click the link it shows the derailleur. It says it’s a sis 7 shimano derailleur. Jul 19, 2020 at 10:01
