Starting with full disclosure: I ride a 2009 Giant TCR Advanced (not SL). Nevertheless I see a lot to criticize in the video. First the measurement unit errors mentioned above. Second the relative weights of the three Giant frames. My M frame actually weighs 1,207 g, not 968 despite being reviewed in magazines in the 900 g range. And third, 250 g for a top-of-the-line, light weight seat post is disingenuous. The Performance post I ride is only 150 g and similar weight posts are readily available. Removing that 100 g difference from all the non-ISP listings in the chart would make a big difference in the standings. I don't know why Giant did things this way. Being number one (as they readily admit) isn't all that important. Being close in weight and in the top three or four would suffice for most marketing purposes, especially if the stiffness results are real. This would be a great presentation if it had been done properly.
