Treadmill scraping noise middle of a run?
I have a fairly new Sole treadmill. Probably between 100 to 200 miles on it. I’m getting a strange scraping type noise coming from the rear of the treadmill . It usually starts around mile 3-4 of a run and sometimes it will only last for less than a minute but will come back a minute later. I’m not running that fast either so curious as to what it could be. Any thoughts?
