Newly designed shifter for Shimano's Di2 wireless drivetrain system

The shifter switch with SHIMANO RAPID ES provides tactile feedback for improved control, a characteristic perfected over generations of mechanical shifting development and proven with XTR M9200. The new switches can be placed in more locations on the bar, while the button functions can be optimized for different riding preference, allowing riders to dial in their setup just the way they like it
