When setting the rear gear cassette ratio for Shimano 12 speed, the Garmin 530 only shows x11 in either singular entry or preset entry within the Di2 sensor set up.
Thanks for the advice. Where about’s do you enter “automatic”, I presume you mean the Garmin 530 head unit. My cassette ratio values are entered in the E-Tube app, like you have mentioned. I appreciate your help.
