SRAM introduced these rd designs with their 1X systems. To me they seemed counter-intuitive. My first thought was why would any manufacturer drop the slant from the parallelogram (pun intended)?. The early marketing graphics that show how the it works are really too simple in explanation. It's now 10 years since introduced. Does an observation of built-in yaw mean that the parallelogram is uneven - so slightly trapezoidal? There's a lot going with these mechanisms. Great work - interesting and engaging stuff to follow.
I assume that the parallelogram is indeed more like a trapezoid. I don't see any other way to produce the yaw. That being said, I've noticed this yaw on a lot of slant-parallelogram derailleurs as well.
I really like your way of presenting the results of this rather niche topic. Thank you for the insights shared here and in other videos!
