The day has finally come! Shimano has released their latest iteration of the Dura Ace Groupset for road bikes. There are some big changes and improvements to mention. Let's get started by looking at how we got here. Over the last several years, both SRAM and Campagnolo have made strides in their groupsets and technology. Both going 12 speed, SRAM launching AXS, and having their shifting catch up to Shimano performance. It was a matter of time before Shimano made the jump to 12 speed and, did we mention the semi-wireless shifting? Well, let's jump right into it. 

5 Things To Know About The New 12 Speed Dura Ace

1. The new drivetrain will be 12 speed and will offer wider gearing options. This is probably the biggest, most noticeable improvement. Furthermore, Dura Ace is now an electronic only groupset. Moving away fully from any mechanical shifting. 
2. The new 9200 series will also feature Servo Wave technology in the brake levers, as well as a better rotor design borrowed from the MTB side of things, which together will offer better modulation and stopping power.
3. The new drivetrains will also only be available in an electronic "Di2" format, but will change to a partially wireless setup and will boast better battery life than its predecessors.
4. The new Dura Ace and Ultegra will be more ergonomic at the controls, mimicking the lever feel of the GRX Di2 group.
5. Finally, the performance of shifting, and rigidity at the crankset will be improved over 9100/8000 series.
