FREE SHIFT for e-MTB helps you emerge from every descent and corner with the more controlled flow by eliminating the need to pedal while shifting.
FREE SHIFT is available on compatible e-bikes with Di2 shifting. While coasting, the drive unit uses just enough power to rotate the chainring and cassette to smoothly complete shifts and does not affect the acceleration of the e-bike.
AUTO SHIFT while pedaling is compatible with e-bikes equipped with Di2 shifting and an 11-speed or 10-speed LINKGLIDE drivetrain.
AUTO SHIFT while coasting is compatible with e-bikes equipped with Di2 shifting and a 12-speed HYPERGLIDE+, or a 10-speed/11-speed LINKGLIDE drivetrain.
