Afternoon all,

I am converting a Salsa Black Borrow 1 Fat bike over and using a rear wheel kit. The bike as a 132 mm bottom bracket with a press fit 41. What type of pedal assist sensor would work with the bottom bracket?

Thanks
Bob

Since the BB has outboard bearings, you may need to go with a drive side PAS that mounts to the chainring rather than the spindle.

See the one labeled "PAS 12 Pole, Chainring"

+1, since i have a direct mount chainrings i epoxied a regular PAS ring on that i bored the center from. i think grin has bolt on for regular 64/104 or 58/94 bcd though. the sensor mount will be dependent on the frame but shouldn't be too hard
