( https://bike.shimano.com/e-tube/project.html )

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.
