Experiencing a strange jamming/resistance in the rear EC70 hub...if I tighten the QR appropriately. If it is looooooooose (Too loose for common sense and safety...) it will spin correctly. Also have a chain suck problem if its appropriately snugged. Initially thought the BB was grenaded, and replaced same, but now thinking its the freehub. How does one test/diagnose freehub issues?
This is the same bike that took a bite out of the last cassette it had mounted on it...
