Hi all,

I bought this fully internal frame too and built it up with an Shimano GRX 820 (1x) mechanical groupset with the 10-51 cassette. The build went really easy until I got to adjusting the deraileur...
I can't get it to work properly... It shifts very inconsistent.

Is there anyone with tips to get it to work properly? (Maybe a youtube video I haven't found yet) I am affraid that the cable is routed to tight through the frame I used the deraileur outer cable completely through the frame and handlebar.
 
Thanks in advance...
