Yeah, a buddy of mine just got a new bike and would not stop complaining about this rough spot in his pedal stroke. He was convinced it was his form or something. I finally talked him into letting me check the crank alignment, and it was way off. We got it dialed and he took it for a spin. The text I got was just, 'oh... THAT'S what it's supposed to feel like.' It's one of those things people don't notice until it's fixed, and then it just clicks.
One thing that gets overlooked is how off-kilter cranks speed up chain wear. The uneven pull stresses the links differently, so they stretch out of sync. Before you know it, your shifting goes haywire and you're replacing chains twice a year. I've watched friends blame their derailleurs for rough shifts when the real culprit was a bent crank arm. Getting that alignment sorted isn't just for comfort, it's a cheap way to avoid bigger drivetrain bills. Have you ever sorted a shifting problem by adjusting the crank instead?
