They did not give any specifics, but the video clip I sent them showed that at low flywheel rpm, there was a sound that could be heard, similar to the clicking but just softer and deeper. Funny thing is, that sound could literally only be heard during a short window before going away and not being able to be reproduced, which I mentioned to support. The local support immediately requested that I submit a ticket so that they could get a replacement unit out to me.
