I have a Emonda SLR with Red 22 mechanical, upgraded to eTap. This week, i'll be on vacation and rented a Emonda SL6 with Ultegra. I've not ridden Shimano for a few years so i'll now be able to compare it to my usual groupset. The biggest issues is the shifters but i'm sure i'll get past that and evaluate the drivetrain.

Red 22 has been flawless so the bar is set high.
