AUTOMATIC SHIFT

DI2 compatible Inter-5E with SHIMANO STEPS E6100 series and E5000 series offer full automatic shifting. The SHIMANO STEPS
system automatically selects and shifts into the optimum gear, based on the number of crank rotations and speed.
Also, riders can always manually shift into the gear they want, even in auto mode. When they do, the SHIMANO STEPS system
uses a learning function to recognize the manual shift operation and automatically fine-tunes future automatic shift timing to the
rider's liking. This offers a stress-free ride, eliminating the need for the rider to worry about whether they're in the right gear or
have to change gears after an abrupt stop.
SHIMANO STEPS computer-assisted shifting system provides a more responsive and stable shifting performance. This
innovative system monitors rider's motion and determines the optimal timing to momentarily decrease power to the
pedal-assist motor. The temporary reduction of chain tension allows the gear movement of drive train to function
smoothly and unimpeded.
