Hello,
I ran into a problem when moving my rear hub motor kit to another bike frame that has a Race Face Atlas crank and bottom bracket installed. My PAS sensor disc is made to mount on smaller spindles, but won't fit on the over-sized spindle that Race Face uses.
I was about to give up and switch out my cranks and bottom bracket, but thought I'd ask here to see if anyone has encountered this and has a solution. I read another post of a member gluing the sensor ring to his crank on the chain ring side, so one thought might be to add a washer between the right crank arm and the bottom bracket/sealed bearing to create enough space to do something similar.
Anyway, any ideas are welcome.
Thanks!
 
Best first suggestion is just to take the magnets out of the PAS ring and stick (glue, etc) them to the inboard chainring where they'll pass the sensor. Just mark them first so you know which side is which, and put them on the chainring the same way they were on the PAS ring.

Or enlarge the hole in the PAS magnet ring until it *will* fit over the shaft.
