No, not if you carefully measure the distance from the hub to the magnet along the spoke on the old wheel and then on the new wheel put the magnet 12.5% farther away. If it seems you’re going too fast or too slow then it actually should be 12.5% closer to the hub. < — Math ( 36-32 ) / 32 . I can never remember which direction you’re supposed to move it (Don’t get me started on Italian threaded front hubs).

If you already took the magnet off the old wheel, you’re screwed and will have to recalibrate.
