On the barbecue this week, the Giant TCR. This was long believed to be one of the better bikes for QA/QC on the market. It turned out to be a bit of a shocker. The bottom bracket was found to be massively undersized and the internal finishing was riddled with displacement voids (wrinkles).
Of note is the fact that the majority of these defects would be out of sight of the average customer. A borescope was required to examine the insides of the frame. The bottom bracket was found to be out of specification with a 3 point bore micrometer.
A video showing the findings is below
