Yeah, but on the top of the wheel where it's easier to watch.....maybe taped to the fork or something like that....locate it close to the wheel and spin the wheel, then do the same thing with your pencil almost touching the top of the tire.
Can you pin it down to front or rear? Do you feel it more in the seat or the bars?
Definitely more or exclusively on the bars in the front... at 75 if you counted one one thousand two one thousand it would be cycles of fade shake fade shake fade shake etc
