I give up. I've meant to write up a blog about the clinic after editing the video, but it took me forever to get to the video editing, and I still cannot find time to write a long post about it. So, I'll be brief. I found out about the clinic from an MTBR thread. Signed Erik and myself up and also we encouraged our friend Derek to sign up. We showed up in Fairfax on time and found ourselves among a dozen participants. Jiro did a great job explaining track stand, demonstrating manual, j-hop, etc. We all had a great time at the 4-hour camp.
Here is the video I put together.
And following is the video on Bikeskills website:
