About the multi-shifting function
Connecting this system to E-TUBE PROJECT and switching [Multi shift] to [ON] will allow you to continuously
shift gears while the shift switch is held down. When modifying this setting, carefully read “ Items
configurable in E-TUBE PROJECT ” in this dealer's manual.
Gear-shifting interval
[Gear-shifting interval] can be set to one of five levels as a multi-shifting function setting in E-TUBE PROJECT:
[Very fast], [Fast], [Normal], [Slow], or [Very slow] (Default: [Normal]).
A faster [Gear-shifting interval] setting will result in faster gear shifting. The rider can quickly adjust the
traveling speed and the speed at which the crankset turns (“cadence” below) in response to changes in riding
conditions.
However, if a gear shifting operation is performed at an insufficient cadence when the system is set to a fast
gear-shifting interval, the chain may be unable to follow the movement of the rear derailleur, resulting in the
TO ENSURE SAFETY

following problems:
The chain may slip over the tip of the cassette sprocket teeth
The cassette sprocket may deform
The chain may break
Fully understand the features of the gear-shifting interval, then set the gear-shifting interval according to the
riding conditions, such as the terrain and the riding style of the rider.

Gear position control
About gear position control
This gear shifting system is programmed to prevent certain gear positions based on combinations of chainring
and sprocket, in order to maintain appropriate gear shifting performance. Therefore, gear shifting operations
may differ from the basic operations of the shift switch.
When shifting the front derailleur
When the chain is in the position indicated as (1) in the figure, operating the shift switch for front gear shifting
does not shift the front derailleur. Instead, the rear derailleur is shifted to the largest sprocket side by two gears.
