The problem began on a long ride roughly 1 week ago.
I was riding with my headphones on and felt a slight "pull", it felt like a tad bit more than a minor crack in the roadway. I immediately felt the bike began to "drag" and my mph avg dropped 2-3mph. I can't tell for certain if the problem only happens when I stop pedaling, but I do know for certain that while I pedal it demands more effort. I removed a tire thread that peeled off of the sidewall and wedged itself between the hub and the wheel assembly.
I'm guessing that there is still some thread stuck between the hub and the wheel assembly.
Sluggish (2-3mph drop)
Pedaling the bike (inverted) the pedals continue to spin with the wheel.
Running the freewheel counter-clockwise moves the wheel itself.
I have a bad tendency of over-tightening my skewers. (Add to problem?)
Any opinions are highly appreciated.
