Hey guys. On some shifts (4/12 or 7/12) I can hear this periodical chain sounds like if it was in contact with a derailleur plate. The bike is new and also after a LBS review. The high and low limits are set right I guess. The problem is with a shifts that are right before auto trim adjust. It is shimano 105 di2. Any suggestions? Doesnt sound normal to me. Thank you!
