What do people think of this, which I came across on Weight Weenies? These numbers seem disproportionately large compared to what Cervelo has published for the SLC (now S-series) as compared to the R-series.
Eye-balling it yields 125 watts (Litespeed) versus 141 watts (control ) @ 30 mph. Presumably that includes wheels, and presumably they’re the same wheels, since the body typically contributes twice as much as the frame, and so you’re up close to 400 watts not even counting rolling resistance or drivetrain losses. But if the bike was tested w/o rider but with a saddle, for example, that would add wind resistance, perhaps, compared to the component of wind resistance due to the bike with the rider in place.
With such big numbers it would be surprising any major pro race in Europe would be won by a round-tubed bike.
