As I've posted previously it would be very hard to have a 'manufacturing defect'. I can tell you with absolute certainty there are no 'seams' in that area. There are probably some overlapping pieces in specific areas for added strength but at the very least there are 3 layers of carbon that run the length of the stay. Also see the photo of the bike w/ the missing stay. Many bikes today could probably be ridden without seatstays.


You don't understand how this process works. The resin is already in the carbon when it's manufactured. The bike factory doesn't add any. That's why it's call PRE-PREG. 'Voids' are not all common when pre-preg is used. You should do some research before making such uninformed posts.
