This place needs an enema
As I mentioned, I don't know Lee. And I don't keep up with other bike fitters either.
The article caught my eye largely because I've read Joe Lindsey's writing for years and I have a lot of respect for him. He doesn't write anything he can't prove, he actually rides, and he thinks a lot about what he's going to write before doing so.
Those things used to be assumed, but it doesn't seem so anymore.
I was also interested in the article because I know way, way, way more people for who modern LLS doesn't work than for who it does.
