Re: Re:
I downloaded the video and went through it frame-by-frame.
1 - He coasts to the apex of the turn, right where the rear end of his saddle is at the start of the first "a" in the first "kalas" on the banner. Right crank at 6 o'clock, no crank rotation.
2 - He starts to pedal, the right crank rotates to about 7:30 o'clock by the time his saddle is at the start of the second "a" of the first "kalas".
3 - Something goes wrong (some mention of chain jump in Cosmo's post), he stops pedaling and actually backpedals a fraction, the right crank rotates in reverse and gets to almost 6 o'clock by the time his saddle is at the end of the "s" in the first "kalas".
4 - He starts pedaling again, the right crank is at 9 o'clock by the time his saddle gets to the start of the "k" in the second "kalas".
5 - between those two points (saddle at end of "s" and saddle at start of "k"), if you go frame by frame and compare the rotation of the crank and the rotation of the rear rim, you see (a) the rim rotation speeds up right when the crank starts rotating again, and (b) the crank rotation rate and the rim rotation rate speed up together, as he exits the corner.
In other words, it looks okay to me. I think what fools our eyes is the brief interruption where he backpedals for an instant.
I don't know if you are using a Mac or a PC. On a OS X, you can record streaming video from your screen, using Quicktime Player, then use cursor right and left arrows to step through the video frames. Pretty handy. There must be a similar trick for Windows, does anyone know it? I use Windows 10.
