About The Multi-Shift Function - Shimano Ultegra R8050 Series Dealer's Manual

TO ENSURE SAFETY
„About the multi-shift function
• On this system, the multi-shift function can be configured using E-TUBE PROJECT. The gears will continue to shift when the shifting switch is pressed
using the multi-shift function. Shifting speed setting for multi-shift can also be modified. When modifying the gear changing settings for multi-shift,
carefully read "Settings customizable in E-TUBE PROJECT" in this dealer's manual.
• If crank revolutions are set to low under faster setting of the multi-shift shifting speed, the chain will be unable to follow the movement of the rear
derailleur, possibly leading to issues such as the chain slipping over the tip of the cassette sprocket teeth, the cassette sprocket deforming, or the chain
breaking.
