Not as late-to-the-game with this little gem as I might have guessed. With less than 5000 views since it was first posted in July, it's apparently taken a little time to gather steam. My fellow bike-riding weather-wonker (yes, that's really what we call ourselves) Joe (Rockman) shared the link with me via the email earlier tonight. And I, doing my due diligence, will now share it with you.
If you've been riding mountain bikes for a while, like say for the last 10 or 20 years, I think you'll think it's especially clever. At 4:30, it's a bit longish; granted. But give it a chance. It's funny. Smart. Self-deprecating. And surprisingly thorough.
