Re: Climbing

Travis you made me a little uneasy. The reason is that I was convinced that the iBike uses atmospheric pressure as an altimeter, but does not use it to compute the slope. In stead it uses the vertical acceleration as an electronic level to measure slope. The vertical accererometer has a much greater...

Re: Is changing position (and CdA) really a problem? Answer= no!

Indeed there is no mathematics involved because it is simply wrong. FTP is weakly coupled to position, while CdA is much more strongly dependant on it. The proposed maths states that FTP and CdA are couipled in exactly the same way to position. There is absolute no supporting science for it. Just us...
