I guess it comes down to how much of that advantage is attributable to the bars


Indeed, it does - and based on other, independent wind tunnel data, it appears to me that the use of a non-UCI legal bar on the Speed Concept OCLV could account for its lower drag relative to the P4 at all yaw angles.

Indeed, even if you just rely on Trek's data (for the Speed Concept TCT) the Speed Concept OCLV version appears that it would be faster than the P4 only when the average yaw angle is >15 deg if both were fitted with UCI-legal handlebars.



There's independent data which shows a non-compliant vs compliant bar (variant of the first or otherwise) drag differential on the order of 125-175g out at 10-15deg yaw? That's Huge. Where do I look for the details on that testing?


1) I said based on other, independent wind tunnel data.

2) I didn't say publically available.

3) I stand by my conclusions (specifically as they are written).
