As a frequent bike rider, your research is both relevant and informative, thank you. Regarding this newest injury, I hope we can agree that we the fans are less impacted than Chris, or Chaim, or his Red sox teammates, or the owners. I'm on board with lamenting the fact that he's hurt AGAIN, and that he should have taken more care. I just wish we could pull back from the personal attacks on players from whom we want and expect more. I hate the expression due to its overuse, but "it is what it is".If you are going to be a pedant.
