Suitability of Shimano Tourney Derailluer
« on: April 10, 2012, 09:29:52 pm »
Needed a long cage derailluer for a larger cassette swap and was given a new Shimano Tourney TZ 50. As it is a "cheap" derailluer I'm wondering if it is a waste of time installing/using it. Also all on-line info says this is for 6 or 7 speed bikes. Will it even work on my 9 speed?

I'd bet it will work (but I wouldn't bet any more than the derailer is worth).  Most Shimano derailers of recent vintage (last 15-20 years) are indexed in the shifter, and most rear S. ders are compatible with each other.

It may be worn, and therefore shift sloppily, though.

How much use do you give your bike?  If you are a very casual, low mileage rider the Tourney should be satisfactory.  As you noted it's the bottom of the Shimano line.  If you ride a lot and expect to do long rides and tours, get something better.

For use with a large cog cassette any of Shimano's newer MTB derailleurs will be fine.  The "Deore" or "Deore LX" models are the sweet-spot in Shimano's range offering good durability and performance.

With a TZ50 Tourney rear derailleur, you are going to be limited to a 6 speed freewheel. This is an older model that has been supplanted by the newer TX35, TX51,TX55 and TX75 6/7 speeds versions. In the old pre-indexing days you might be able to get away with forcing a derailleur to work outside of it's specs, but nowadays trying to mix models or brands will most likely cause problems or just flat out not work.
