    It's a step below the deor stuff. Functionally it works great, but its mostly steel construction where as deor is aluminum. I have the Mountain LX group on a retro 29er grocery getter! It works great!

    STX is where it's at. Just ask Rumpfy.

    I was born with a silver spoon, so I won't settle for less that STX-RC

    The way I determine quality is to out on a stand, remove the upper limit screw, pedal like hell, and push that plastic shifter for all its worth. If it it comes out ok, then you can use going forward

    Cool. I'll adopt that test to my quality testing procedures as well.

    I de-NOS'd a Paul derailleur this way and received positive feedback because the buyer was looking for something that would "make his gears work."

    FWIW the Mountain LX front was the lightest Shimano f derailleur.

    Hate to hear that... I went looking for a top pull to replace my bottom pull and came up empty. I eventually replaced it with the not quite as vintage black LX.
