Thinking of getting an X1 Pro Gen 2 motor for my 2003 Specialized Stumpy XC. They offer three chainwheel options (11/53, 11/63, 12/72) that have different small pedaling inner chainrings, 32t, 38t, and 42t. I am not going to be single tracking this so mostly for higher speed gravel and such. I am inclined to go with the middle option and I believe the 38t ring will clear the chainstay, but since they don't have a drawing to show the chainring/chainline position I am not sure. Anyone done an X1 on a similar bike? Any chainline issues?
edit: I found a drawing on the CYC site. I'd still appreciate any feedback from folks with similar bikes.
edit 2: my bike has 22/32/42t chainrings and, according to their drawing the CYC puts the pedaling ring about where my middle 32t sits, which should be a perfect chainline. So the 11/53 with 32t should work for sure... the 11/63 with 38t *might" work. No way the 12/72 with 42t would fit. That would hit the chainstay almost for sure.
