This economical replacement rear derailleur will provide index ("click") shifting compatibility with Shimano or SRAM 6 or 7 speed shifters, and will also work with older 5 speed shifters in friction mode.
  • Light action design
  • Handles up to a 34 tooth largest cog
Two mounting versions are available:
  • "BOLT-ON, FOR FRAMES W/ DERAILLEUR HANGER" is for frames that have a threaded derailleur hanger to accept the rear derailleur. Such frames usually have a quick-release rear wheel
  • "W/HANGER, FOR FRAMES WITH NO HANGER" is for frames that do not have a threaded derailleur hanger; the hanger is part of the rear derailleur and is held in place by the rear wheel - typically a nutted axle type found on less expensive "Mart" bicycles

    I have an older Schwinn mountain bike and I bought this derailleur to replace the original which had disintegrated. I was really surprised that this derailleur functioned better than my original one had and at such a low cost! I did have to cut the cable and sheathing to make them compatible with this derailleur and it took a few test rides to adjust it to shift gears smoothly- but after that it was perfect.

    I bought this for a sad, beat up, and abused Schwinn S60 to refurbish for a loaner bike. I am surprised how crisp the action is and how little fine tuning was required. At this price point it wouldn't hurt to keep a couple in the garage for emergency spares.

      Comments about Shimano Tourney TX55 Rear Derailleur:

      I use these to replace the stock der on "Mart" type bikes, which is usually a very poor performing unit. In the right version, this will bolt right in place of the stocker and be a easy upgrade.. they definitely will improve shifting. I suggest pairing this with a better index shifter and maybe a fresh freewheel.

      Works really well as a replacement. I have a 2000 schwinn sidewinder with more than 20,000 miles and have gone through many derailleurs but this seems to be the best. It is simple to adjust and accurate.

                Used this as part of an upgrade to an old bike. Now the old bike works better than new and more reliable shifts.

                  Can't beat the price. Went right on my GT Aggressor no problems. Havn't really put a whole lot of miles on it. So good so far for 50 miles.

                    May Not Work on Your Bike

                    Comments about Shimano Tourney TX55 Rear Derailleur:

                    Problem I had with this is that although it is a direct connection, (as opposed to the claw connection) the upper portion acts like another hanger so that once installed, the actual derailleur cage hangs down too far. The connection to your existing hanger is too far removed from the derailleur body. As a result, I later installed a Deore which worked perfecty on my 70's Peugot rebuild.
