Functional and great value
I had an old seven speed derailleur probably from the 90s that "crashed" into a wheel and destroyed it. This replacement worked well without any other changes and the cost was low.

TourneyTX Shimano Rear Derailleur RD-TX800 2015 Jamis Durango Sport
I purchased this Tourney Shimano Rear Derailleur RD-TX800 for a used 2015 Durango sport. I purchased the bike used and the derailleur and hanger were both severely damaged by a fall the previous owner had taken. I didn’t want to mess around with figuring out a higher-end performance part, so just went with the exact same model derailleur. It arrived well packaged and works exactly as it should. It is by no means a light or quiet product, but it will serve its purpose. I have only had it on the bike for three months and maybe 100 miles of paved trail riding. No issues at all.

Lifesaver for getting my bike running
I had to replace the previous one when I got ran over. This one wasn’t identical, in fact it actually made the gear change even smoother than the one that originally came with the bike. It looks very durable and can be easily adjusted to fit your needs.

Great value
Fit perfectly on my Schwinn bicycle! Super easy install -just a few tools required-easy adjustment. Shifts smoothly. Looks to be all metal unlike my oem one. Great economical solution !

Low end derailleur that is surprisingly high end
It used to be that the Shimano Tourney line of components were the lowest 'named' line in Shimano's bike component hierarchy (Tourney up to XTR). But over the last decade, Shimano has gradually replaced the heavy cheap steel in the Tourney line with more aluminum and tighter tolerances. I wanted a full seven speed transmission for my small son's new bike and decided on a full seven speed back, three speed front (21 total gear combos) Tourney drivetrain. I decided to order this derailleur which works with seven or eight speed rear cassettes and figured it would come made of steel. It came and turns out be fairly light weight (290 grams) and is almost all aluminum with sealed bushings. He has been using it for three months and it has worked perfectly and precisely so far. Five stars.

Works well with shimano grip twist shifters
These derailleurs are what you will need for shimano grip twist shifting. I used mine for a 7 speed freewheel rear cog set.
