Upgraded my 11 Speed Dura-Ace to 12 Speed. Curious about the Design / mfg + Looks.
It also helped clean up the cockpit by eliminating the lever wires.
Shimano just works well - Yes, I'm a Shimano fan using Ultegra (big bang for the buck) and Dura-Ace.
11 speed Shimano (Ultegra & Dura-Ace) shifts fast - 12 speed is even faster.........smooth & quiet too
Happy with purchase
