Has anyone had any issues with their WTB saddles (specifically the Volt) making noise from the underside of the saddle. The noise emanates from from plastic molding where it makes a cracking/popping sound. I can push on the saddle and it makes the noise, although it is not as pronounced as when I am seated and riding. This is the second WTB Volt saddle I have had this issue with. The previous versions of the Volt saddle were fine. I have tightened the small bolts under the seat which run around the perimeter of the saddle which seemed to help a little. I was just wondering if anyone has had issues with theirs as well.
