Yes, the B screw pushes against the hanger but for some reason the ring where the B Screw is attached moves independent from the rest of the derailleur. So screwing it in moves only the ring. To my understanding the B screw and the rest of the thing should move together.

Thank you Serge,
The brakes are zrace, so it is basically this set (but I ordered the brakes separately. Breaks are good and light (there's is a trave velo video on them) l. Bleeding was a bit funny as they have two screws for the oil (for unclear reasons) and non of my adapters out of two kits fitted (browed one in the end from a friend).

Thanks but I tried that. Screwing it in didn't have any effect. I feel something with how it is installed might be wrong.

Hello,

I recently finished my first build with an TanTan TT-X34 Frame and an Ltwoo RX hydraulic group set (yeah :) ). I was able to adjust the shifting to an ok grade but I struggle with the position of the (rear) derailleur cogs. On the low gears the cogs of the derailleur are touching the cassette (see pictures)
The little screw that suppose to change the position of the derailleur ram doesn't have any effect (picture with red arrow).

I feel something is wrong but I don't get it.
Cassette is a SRAM force one.

Any idea how to solve this?

Thanks in advance and best regards!
