Please help me to identify this part. The pictures show rear wheel.

Picture 1 Picture 2

UPD: It is more like an adaptor to connect to the bicycle.

  • Is it even "a part"? It looks like it's just a piece of decorative trim on the gear mechanism. – David Richerby Jun 5 '17 at 7:38

    If you open the screw visible in the bottom picture, I believe you can pull away the gear-changing mechanism and the plastic part will stay attached to the hub. It belongs to the pin that is actuated to change gears in the hub. – Christian Lindig Jun 5 '17 at 7:49

    I'd call it the "adjustment indicator" and you view it through a window or viewport. Setting the cable tension right should result in the indicator (triangle or arrowhead) being between two lines in/on the window. – Criggie Jun 5 '17 at 10:51

    Its very unlikely to be a part you can order directly. More probably you'd need the whole unit. Or find/buy a donor bike and scavenge parts from it. – Criggie Jun 5 '17 at 10:52

I believe the plastic part is similar to the one identified by number 21/22 in the diagram below. I don't have a name for it, though. I am also not suggesting that this is the exact model that is on this bike but I believe it is the same principle.
