Re: Aero bar power drop...
Of course one must find a good riding position, when using aero bars.
Moreover, I have rarely seen a good position when installing aero bars on a classical road bike, without changing any parts, or at the very least, moving the saddle a bit forward (and higher very often).
How do you call the part on which the handle bar is fixed? A seam? A seant? Whatever, that part often need to be replaced too.
But more aero, means less power.
|We concluded that riding a bicycle in an extreme aero-position increases the metabolic cost of cycling when wind resistance is not taken into account. However, when the mechanical power losses of 9 W (estimated by the [spacing dot above]VO2 increase) are compared with the expected aerodynamic power savings of approximately 100 W, it appears that aerodynamic advantages by far outweigh their metabolic cost
That is one, there are probably others where power got measured with a power meter, instead of being estimated.
** Edit ** I found at least one that contredicts.
Here, anaerobic power got tested. Two groups. CT=Cyclists, AT=Triathletes. For some mysterious reasons, triathletes could maintain a higher avg power on a 30s duration, in aero position, compared to upright position.
But the peak power output was higher in upright position for the two groups.http://www.asep.org/jeponline/issue/.../PevelerV2.doc
