Non Tribuo Anus Rodentum and off to the next adventure (RIP)
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.
Pictures really help. Roger

Otherwise I have no idea.
