Shimano Dura-Ace Di2 R9270 12 Spd Road Shift/Brake Lever

Shimano Dura-Ace Di2 R9270 12 Spd Road Shift/Brake Lever Introducing the Shimano Dura-Ace ST-R9270 Di2 12-Speed Shift/Hydraulic Disc Brake Levers. Shimano's wireless Dura-Ace cockpit delivers a clean aesthetic and simple setup while reimagined ergonomics bring a new level of comfort and control. The Dura-Ace hoods are taller with a slight curve inward for a more secure, natural perch over any terrain. The lever body reach is also extended by 4.6mm to create more space between the brake lever blade and the handlebar. The new Dura-Ace Di2 lever switches are also redesigned for better control and easier access. The longer switches are easier to reach when riding in the drops and an increased offset between the switches makes them easier to differentiate while riding. A third switch on the hoods continues with the new R9200 series shifters. A set of new remote switches provides multiple shift points with options for the tops as well as the drops. So whether climbing at your limit or sprinting for the line, you have can control your effort. A new Shimano E-Tube Project App (version 4.0.0) offers intuitive operations for personalizing the DURA-ACE R9200 drivetrain. Offering a suite of customizable, riders can choose between different shift speeds, customize shift button mapping (what buttons perform which functions), program different automatic shift modes like Synchro and Semi-Synchro shifts, fine-tune shifting, and connect with third party bike computers.
