Been happy with my Di2 version, particularly shifter hood size.
However the hydraulics have been an absolute pain to get right Manufacturing quality is a bit poor had to warranty my shifters as the 2mm bleed port rounded off.
This happens on all series, from R9170 down to R8020.
Problem is that Madison still doesn’t stock the replacement. We have like 20 of them in back order just in case.
That bolt is seriously made out of butter!
