For me, it’s about the entertainment value. And I do think I can learn from some of their tech videos. For instances, obviously, they are sponsored by park tools. By servicing tubeless, or adjusting your derailleur is similar whether you use park tool, ride SRAM or Shimano, or whether yo run Schwalbe or GP5000’s.
What I do find annoying, however, is that when they are sponsored by one brand (Canyon comes to mind), they more or less tend to ignore most other brands largely. They almost never do bike reviews, and never do affordable bikes (besides Canyon).
