I got feedback from Chance Glasford and Jed Olson on my pumping flat ground video that I posted yesterday. Their main advice: learn on my 24-inch Scott Voltage dirt jump mountain bike, not my 29’er. The large wheels make it too difficult.

Griff Wigley, pumping flat groundSo last night I took it out and within 5 minutes, I could feel the difference. And in about 15 minutes, I was ecstatic.  The bike was responsive and it seemed like I was ripping around. I took some video but when I watched it, I was surprised at A) how far from the correct attack position I was; and B) how little pumping I was doing with my arms and shoulders.

I watched Lee McCormack’s pumping flat ground video again and took these screenshots to make myself more aware of both problems:

He’s really crouched low. And his arms and shoulders are pumping like pistons.  So I practiced for about an hour today and then captured this 45-second video:

As you can see, I’m still not low enough in the attack position.  And I’m just starting to get the timing right on the arm/shoulder pumping motion.  I was doing it right in the first 10 seconds but then kind of lost it after that. … Read the rest

Learning to ride

I’ve started recording video of my riding to examine my attempts to get better at various mountain bike skills.  I generally prefer to showcase myself succeeding, with an occasional crash thrown in for comic effects. But I decided it might be helpful to blog my attempts to improve, especially if it includes some self-analysis as well as links to other coaching videos that I’m watching.

I first noticed instructors demonstrating ‘pumping a flat surface’ in two videos on cornering, specifically hip flexion:

And then I discovered MTB coach Lee McCormack‘s blog posts about pumping a flat surface (here, here, and here) where there are lots of pointers and helpful discussion.  He links to a video but it’s in native .mov format on his server. Here’s the YouTube version that someone has uploaded. It’s pretty amazing to see how fast he can get going:

He also points to how Brian Lopes applies the same pumping motion in this Pinkbike video:
