Just received our Rad Mini & Rad Mini ST and have been out riding a few times. My wife's step thru has about 10 miles on it and has developed a rubbing noise which was coming from the pedal area. After trying to recreated the sound we located the problem and found that the shifter cable had moved over and was rubbing on the inside main sprocket guard. There is a minimum of 1/8" clearance between the cable and the guard. I our case it had already started to cut into the shifter cable were you could see a v stating to form.

Has anyone else had this issue and how did you fix?
