Shimano Tourney TX55 Rear Derailleur

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 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.

I used this to replace the OEM rear derailleur on my son's Specialized Hotrock 6-speed that had one too many tumbles onto the sidewalk. Fitment was fine but the cage hangs kind of low for a 20" wheeled bike.

PS, if your kid is riding a geared bike - make sure you install one of those derailleur guards.

Comments about Shimano Tourney TX55 Rear Derailleur:

I bought it to replace a "mart" bike and I can not complaint. Shimano makes good stuff and the price was the best. A little heavy in the downside but no big deal.

Comments about Shimano Tourney TX55 Rear Derailleur:

This derailleur was used to replace an OEM Shimano model. It fit perfectly and was relatively easy to adjust. It does not shift perfectly but it does work pretty well. The high and low gears hit exactly, but there is an intermediate gear that does not always change. All in all, it is not bad for the price.

    I bought this to replace the unit on my girlfriends bike which her old one was all kinds of bent and busted. This unit does as promised and has renewed her riding enthusiasm.

            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.
