Know before you buy
No, the R9270 levers are designed specifically for the 12-speed Dura-Ace R9200 series. They utilize a wireless connection to the derailleur and are not backward compatible with 11-speed Di2 systems or mechanical drivetrains.
While the shifters themselves communicate wirelessly with the derailleurs, they are typically connected to the main internal battery via E-Tube wires to ensure consistent power and system integration.
Yes, you can fully customize the button assignments and shifting logic using Shimano’s E-Tube Project app. This allows you to tailor the shift patterns to your personal preference.
Absolutely. The integrated hydraulic disc brake system is engineered for consistent, high-performance stopping power in both wet and dry conditions, providing reliable control on technical descents.
