Edit: after some research I see thatShimano calls it Free Stroke Adjustment. I will have a go at this. Thanks!
Edit2: not possible with grx600 levers.
Hmm, that’s annoying. Only other trick I can think of is take the wheel off, pull the lever slightly (to bring the pads closer together by a fraction of a mm), reinstall the wheel and see if it’s better (or if it was too much and the pads are now rubbing, and you now need to re-centre the calliper or push the pads apart...).
The calipers where fiddled with yesterday and pistons pushed here and there :-) its better then it was but still close. Not having the free travel adjustment is pretty shit when its obviously possible.. i guess ill have to get the 800 levers if the 600s ever break/wear out.
