    Shimano Tourney derailleur with 15T and 13T pulley wheels?

    A workmate wants me to repair the drivetrain of his wifes trekking bike.

    The bike has a 3x7 drivetrain.

    I....I have never seen such a run down drivetrain in my entire life.
    All teeth on both the freewheel hub and the crankset are freaking pointy and missing or borken teeth are everywhere.
    The chain wear is not measurable anymore and it snapped one time. He just pressed the chain links back together somehow.

    I have to replace everything.
    But the derailleur?
    It is a Tourney with a very short cage and 15T and a 13T pulleys.
    Of course the pulley are also dead at this point, almost round.

    But I can't find any spare parts online, nor can I find the model.
    The derailleur pretty much looks like this but with a Tourney logo on it.

    The bike is 6 years old.
    Is there somewhere a pulley set for 15T and 13T to buy for this Tourney?
    Maybe I should just buy some chinese ones on Aliexpress or Ebay

    A complete derailleur will be a cheaper and better solution, an Altus derailleur is about $15 and you could probably buy a Tourney for $10.

    I know, but the derailleurs still works without any issues and he don't want to spend too much money.
    I found this here on Ebay.

    It's the pair for the Altus.
    This should work on the Tourney too, right?

    Those might work but a complete derailleur is essentially the same price.

    Ahh gee.
    I will ask him about it. But I think he will take the pulleys.

    OK, ~$10 for some pulleys that might fit an old worn derailleur over a new ~$10 derailleur that will for sure work doesn't seem like the best deal to me though.

    I guess there aren't spare parts because Shimano considers them essentially disposable.

    At this price point I can understand why Shimano would do that.
    I will see tomorrow.

    If the drivetrain is as worn as you say, the derailleur will be gubbed. You might only notice the worn pulleys but the pivots will be worn out too. Do not waste money on new pulleys, bin the whole thing.

    There are a plenty of 13T and 15T CNC machined pulleys on Aliexpress. Some even with ceramic bearings

    Anyway - the model might be TD-TX31. It was even available with smart-red tension pulley

    A little update.
    He didn't like the "new derailleur" idea just as I thought so we did go for the pulleys.
    Those Altus pulleys are literally the same ones that are on the Tourney so they fitted perfectly.

    After a good clean up of the Tourney it looked as good as new.
    Shifts nice.
    A new 7spd Sunrace freewheel cassette, new Shimano 3spd crankset and a Sram 9spd chain are the rest oft the parts.

    Now his wife can ride again without complaining :P

    I remain mystified why your "customer" wouldn't want a new der for just a couple bucks more?

    If it were an out-of-production Campy, I could understand, but this baffles me.

    Looked to me like it was same price. Doesn't matter though, the customer is always right.

    People like that usually end up costing themselves money. They are too stupid to understand when spending is the wise option in the long run.

    Sometimes I'll just refuse to do things. I won't work on SRAM brakes for instance.
