Anyone have a problem with their front bike fenders cracking. I put mine on and they both crack within 30 miles of driving. The crack is right at the edge of where the thick inside flat wall meets the top thinner curved piece. See pic I did modify mine by rounding the front and back cutting some off of the inside flange. It doesn't seem like that would make it crack so quickly ( from vibration?) but I'm looking for some thoughts on this. The fenders sit about 3/4" off of the tire. Thanks.
