All ya all are missing the point with the exception of fietsbob. m2005's derailer is grinding against the spoke protector when he is in low gear. The lower limit screw could be adjusted to move the derailer outboard a bit if the pie plate protector is straight. Or he could remove the spoke protector (it's also known as a "dork disc", m2005) and be a whole lot faster, 'cause that thing weighs about 3 metric tons!
