thanks to you both

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

I wasn't trying to be rude. But you could just measure from the center of the motor out and see that motor is shifted to the right about 30 mm on a 73mm BB. On a 68 mm BB it is shifted 25 mm to the right. That is what I meant by it has nothing to do with frame geometry. No matter what the...

This doesn't make sense. The frame has nothing to do with the crank offset. The bbs02 is manufactured such that it is shifted to the right by 30mm.

sorry, I mean add 30mm more axle and housing to the left side would fix this.

no mine was the 68/73mm model. the crank is way closer on the left chain stay then on the right. It is about 30mm closer to the left chainstay then the right.

I don't disagree that flat pedals can fix it, but if you want to clip in I disagree. I can definitely feel the offset when I pedal with clips. It feels almost like pedaling with my body rotated. In thinking about it, it really is mind boggling that they didn't just set this up properly at the...

Wider apart is better than poor symmetry. Fatbikes generally run wider q factor which you can deal with, but unequal symmetry can really mess with your riding, seat pain, knee, and most importantly hip pain.

Why doesn't someone make a 30 mm offset left crank arm? Seems like that would fix the situation pretty easily.

I install the bbs02, and while it technically fits it doesn't not really fit. The crank arms are way offset. I even put on a 18 mm offset left arm crank and the left is still 15mm closer to the chain stay then the right side. 15mm is quite a bit offset when you arre clipped in and riding...
