Shimano Dura-Ace Di2 R9270

The R9270 system uses a semi-wireless setup. The shifters communicate wirelessly with the rear derailleur, but the derailleurs themselves are wired to a central internal battery to ensure maximum reliability and power efficiency.

The 10% increase in pad clearance is a significant upgrade that reduces the likelihood of rotor rub, especially after heavy braking when rotors expand due to heat. This ensures your wheels spin freely and quietly, even during technical descents.

The system is highly efficient, with a single charge typically lasting between 1.5 to 2 years depending on your riding frequency. You can easily monitor battery levels through the Shimano E-TUBE Project app or directly on the derailleur indicator.

Yes, the brake levers feature adjustable reach, allowing you to customize the distance between the lever and the handlebar. This ensures a comfortable, secure grip and optimal braking leverage regardless of your hand size.

No, the Dura-Ace R9270 is a dedicated 12-speed system. It is not backward compatible with 11-speed components, so you will need a 12-speed cassette, chain, and crankset to complete the build.

The refined ergonomics feature a raised hood peak and an extended body, which provides a more secure hand position. This design reduces fatigue on long rides by offering better leverage and a more natural wrist angle when you are riding on the hoods.
