So I've added one of these shift sensors (that cuts the motor power) with the goal to reduce chain wear on my diy ebike but I kind of fucked up my shifting cable housing during the process and now my derailleur won't shift at all. I have a 7-gear shimano altus shifter and derailleur, and the derailleur only starts moving up on the 4th click or so, even though the tension is high.
This sensor takes in the housing from one side, measures cable movements on the inside and in that case cuts power for a small amount of time. The second piece of housing goes into the rear of the sensor towards the rear derailleur.
For me the only explanation why the shifting is completely fucked up is that the added friction of a slightly pinched housing and the inner friction of the sensor itself makes it impossible for the tension adjustment at the shifter to reach the rear derailleur.
It feels like even a slight gap in the cable housing makes it impossible for the tension to travel all the way back. All of this trouble also led to the cable housing to start splitting and biting itself into my shifter
My plan is to install a new cable housing now, cut it with quality cable cutters this time to avoid pinching, use metal end caps and try again?
I'm a newbie btw so any help is appreciated
