Finally got my conversion done on KHS mountain bike. I’m having chain line issues. Not entirely sure what is happening so bear with me as I try to explain?
I am using a 40t Lekkie chain ring on motor. I have 2-3 mm between frame rail and the ring. I don’t think I can get it any closer. (?)
in the rear, is an 11 speed cassette. on first install, it would skip terribly if you were in anything lower than 4th ring down from largest ring. (Lower meaning larger diameter ring) and it did not like the smaller diameter rings either presumably because they were too high for the speed and weight of me.
Is this normal? I.e. you basically cannot use all the gears when converting to e-bike?
After some research I found guys rearranging their cassettes to get the larger diameter rings in this narrow window of chain line availability. I tried that with little success because the design of my derailleur does not allow the larger rings to be in the chain line window because the chain gets wedged between ring and derailleur body.
So, I am at the point that I either live with it like it is and never change gears, (don’t like that option) or I find a new derailleur that allows me to get larger chain rings in the “window“ so that I have less chain slippage but that means I give up any speed because I’m always in a low gear. I am hoping there is a better option you guys can tell me about.
For what it’s worth, cassette and chain have maybe 75 miles of human powered riding. Do I need to change cassette And chain?
