The new Dura-Ace exploded into the world this week with a slew of technical details, many of which were clouded by the smoke of Shimano’s inscrutable alpha-numeric coding. EW-WU111, anyone? Let me break down what’s cool about the new four-tiered group in basic English.

New Shimano Dura-Ace groupsets, explained
First, a quick primer:
- 9100 is mechanical Dura-Ace with rim brakes
- 9120 is mechanical Dura-Ace with hydraulic brakes
- 9150 is Di2 Dura-Ace with rim brakes
- 9170 is Di2 Dura-Ace with hydraulic brakes
1. Better brakes for Shimano Dura-Ace
Shimano launched a Di2 system with hydraulic brakes in 2013, but refused to peg it as Dura-Ace, saying the pieces weren’t yet refined enough to achieve the top-level moniker. (Contrast that with SRAM, which hit the ground running with Red HydroR.) Now, for 2017, Shimano has a level of hydraulic calipers, levers and rotors worthy of the Dura-Ace designation.

P.S. Those black-interior rotors look bitching.
P.P.S. If you still like rim brakes (I do), then the new 9100 calipers come with claims of boosted stiffness over the already class-leading 9000 models.
2. Better buttons for Shimano Dura-Ace
3. Hidden junction box options for Shimano Dura-Ace
4. Wireless connectivity for Shimano Dura-Ace
- You can now program and update the system via Bluetooth on a smartphone or tablet (hello, iPhone users)
- The junction box now talk wirelessly to your Garmin (catching Shimano back up with SRAM’s current Red eTap)
5. Synchronized and/or customized shifting for Shimano Dura-Ace
6. Power measurement for Shimano Dura-Ace
