5 The Art of Countersteering

I was fortunate enough to land on a video, thanks to My Shaved Legs and user IanJSeattle.. As unconscious a behavior is walking and breathing to humans, so is counter steering to the cyclist (oh of course, most cyclists are human too unless you beg to differ). I find it slightly ridiculous that a big deal is made out of this principle in most cycling books, when in fact each one of us uses it pretty much on a daily basis, whenever we ride.

To handle a corner, you have to effectively lean into a turn so as to shift the combined center of mass of you and your bicycle. If you don't lean, centrifugal forces will disturb the balance of forces and throw you to the ground.


How counter steering works : Source

But the only way to cause that lean is to move the support points in the opposite direction first - a tiny jolt of the handlebars for a fraction of second depending on speed that we aren't really conscious of but it exists, as this video proves with a slow motion camera. The counter steering phenomenon becomes evident when there is an obstacle preventing the wheel from counter steering, such as an overlapped wheel which is a common cause for crashes in bicycle races. Next time, save your bones and equipment by being aware of the need to counter steer.

    I had heard of the concept before but have never seen it explained so clearyly before, so thanks.

    The other important lesson I learned from the video is that flying = bad.

  2. No problems. Glad you picked it up.

  3. I first learned deliberate countersteering on a motorcycle long ago, and as the video points out, it's easier with the greater mass of a motorcycle front wheel.

    These days I teach it to adult bicyclists in a Road1 class. Some are utterly terrified of trying it, although they've been using it unknowingly for all their lives. Kids, on the other hand, are eager to try it.

  4. Um, that's such a load of bunk.

    Slightly ridiculous, indeed! It's made all the more so by invoking the mythical "centrifugal force".

    So:

    Countersteering is dangerous at low speeds.

    Countersteering is invisible at high speeds.

    Countersteering is only feasible and visible at 10-15 MPH.


    Okay. Ha ha. What's the punch line?

  5. I saw another YouTube video about cornering the other day. They were explaining to put pressure on your outside pedal and to force the bike into the turn by putting pressure on your inside hand. I tried this consciously yesterday and was amazed how good it felt. I'm riding bikes since the age of 5 and just because I don't need training wheels and can keep my balance I thought I mastered the skill but somehow to get better, corner faster etc I need to learn technique. So thanks for sharing.
