Description
Specific ergonomics
These shifters have been ergonomically designed to give you more grip and control on rough terrain. In addition to a special shape, the shifters have been given an anti-slip coating. This gives you sufficient grip and control while cycling, even in extreme conditions.
Compatible with all 11-speed Di2 Shimano derailleurs
These shifters are compatible with all 11-speed Di2 Shimano derailleurs. They can of course also be used with the derailleurs from the GRX series. You can set via Shimano's E-tube App on your smartphone whether you want to use these shifters with one or two front chainrings.
Excellent braking power
The caliper in this set uses the same tech used in the Ultegra R8000 calipers. This means that they are designed with Shimano's Ice-Technology and can withstand the heat that can arise during constant braking (brake fade). New to the GRX brake is an extra seal against dirt and mud. The brakes are supplied with Resin (organic) brake pads.

Once Di2 always Di2
Once Di2, always Di2 - even if there is still room for improvement. Shifting precision, always the same amount of force, speedometer control from the handlebar and optional additional shifters and brake levers make the Di2 a valuable and practical companion. What's annoying: The distance between the brake pads and the disc is too small and regularly leads to grinding and squealing, especially when changing wheels, which requires a realignment of the brake calipers. The shift buttons are a bit too small and too narrow to hit the right one "blindly" at all times, especially with long gloves.
