Do 160mm cranks really necessitate adjustments to cleat position, or is this just another myth perpetuated by the cycling community? Ive seen some riders swear by the need to tweak their cleat setup when switching to longer cranks, while others claim its a non-issue. Is there any real-world evidence to support the notion that 160mm cranks require a different cleat position, or is this just a case of if it aint broke, dont fix it? What are your experiences with longer cranks and cleat adjustments - do you notice a difference, or is it all just hype?
