    Shimano rear der identification.

    Shimano bolt on rear derailer, marked RD-AL11 on the back of the paralellogram, looks to be decent alloy & steel construction. Any ideas what it is and where it sits in the food chain?

    No idea. Search turned up not much as you probably already know.

    But if I had to guess, it could be great news or bad .

    One potentials leads is theRD-M511 Deore series.

    Another lead is the Tourney. It's part number is RD-TY18. Maybe this one falls below that?

    It would be great if it were an older high quality part.

    Good luck finding what it is.
