Useful Information

• What are the benefits of using a DI2 system?(N-6060)

  Compared to conventional mechanical derailleurs/shifters,

  • The operation stroke of the shifting switch is light/small.
  • Maintenance is improved since no shifting wire is required.
  • More reliable gear shifting is realized by the automatic trim function after shifting and noise is reduced.
  • The operation is simplified by the Multi-Shift and the Synchronized Shift function. Click here for details

• The SHIMANO STEPS or DI2 system does not work.(N-6050)

  If you connect a device that is not listed in the E-TUBE compatibility table, all components will not operate. Click here for detailson E-TUBE compatibility table

• I'd like to change the assist setting to a more active one.(NP-5080)

  Please change the setting of the riding characteristic by the E-TUBE PROJECT app. Click here for details

• I'd like to change the assist setting to a more comfortable one.(NP-5070)

  Please change the setting of the riding characteristic by the E-TUBE PROJECT app. Click here for details

• I want to change the timing of the automatic shifting to my liking. What can I do?(NP-5060)

  E-TUBE PROJECT can be used to change the timing of automatic gear shifting to your liking. Increase the automatic shift setting value to make the automatic shift timing faster and choose a lower value to slow the shift timing. Click here for details

• Is it possible to shift manually on a slope, etc. while I am using automatic shifting?(NP-6080)

  Even with automatic shifting enabled, you can still shift as needed with a manual switch.With the manual shiftings, the SHIMANO STEPS system will gradually learn the user's preferred shifting timing.

• I'd like to start pedaling with a lighter force than the current setting.(NP-6070)

  If you use an electric internal shifting/internal geared hub/DI2, please enable the start mode setting and adjust to your favorite gear number. Click here for details

• I'd like to shift multiple times in a row.(NP-6060)

  Please use the Multi-Shift function. Long-pressing the shifting switch enables multi-shifting.

  • The combination with the Synchronized Shift function is also possible.
  • If you set an upper gear number limit for the Multi-Shift, the number of shifts at one time can be limited.
  • If you change the setting of the shifting interval, it is possible to adjust to your favorite shifting speed. If the shifting interval is too short, the smooth shifting will not be possible and the chain drop may occur.

  Click here for details

• I'd like to make the shifting operation easier.(NP-6050)

  If you use the Synchronized Shift function, it is possible to automatically shift in conjunction with the front and rear derailleur with just the shift up and down operation.
  Click here for details

• Shifting the front dérailleur changes the gear ratio significantly. Is there any way to improve it?(NP-6040)

  If you use semi-synchronized shift mode, the rear dérailleur will automatically lower the gear ratio when you manually shift the front dérailleur to reduce large changes in the gear ratio. Click here for details

Solution Tips

• Tapping "Disconnect" on the app does not restore the bicycle to a state in which operations such as shifting can be performed.(N-6045)

  SM-BCR2 can only be used with the latest version of E-TUBE PROJECT.
  It has been confirmed that bicycle operations become disabled after SM-BCR2 is used with E-TUBE PROJECT Ver. 4.0.2. In this case, performing the following steps may restore the bicycle to an operable state.
  (1) Update E-TUBE PROJECT to the latest version.
  (2) Connect to the bicycle using SM-BCR2 again.
  (When doing so, use the same SM-BCR2.)
  (3) Disconnect the bicycle.
  If performing the steps mentioned above does not enable operations, the DI2 system needs to be reset. For information on how to reset the DI2 system, contact your local distributor.
