I'm setting up grx 11 speed mechanical and have run into a strange issue.
Had the same kit on the same bike previously and it worked great.
Refitting it now and the upper jockey wheel is grounding out on the large cassette sprocket.
This has to be an error on my part. Any tips on what it might be? I've tried B screw adjustment. Could this be caused by excessive chain length or incorrect shift cable routing into the pinch bolt?
No experience with GRX but had the same issue on 10 speed Record with a 29t rear cassette. If you can't get it to clear with B screw adjustment a shorter chain would pull the mech clear, just need to be cautious of too small for a big/big scenario
