Hello, I just build my new wheel (Hope Bulb 20mm on Sun Double Track) Anyway, i put it in my trueing stand to do it (After lacing it) spin the wheel and theres a noise as though there is a spoke nipple inside the rim. I know its not a spoke nipple becasue sometimes it wont do it others it will, ive shook the wheel countless times and its not a spoke nipple, anyone have any ideas?! (maybe one for Tart :huh:) Thanks in advanced, Jake
