Describing it seems like such a Zen-mystic kind of thing.

And (at least for me) you don't know you are doing it well when you are actually doing it so much as in retrospect. It is kind of one of those things that you realise afterwards, "Hey, that was cool. I totally see what the guys on BF were talking about." And you'll smile. Try and make it one of those things in the back of your mind as you ride, then one day you'll find you are just doing it without thinking about it.

As I think about it, the biggest thing I would say is -- make your goal having four contact points with the bike- your hands and your feet. The saddle is where you rest but it is not a seat. (This doesn't mean you never put your weight on your saddle, it is more about how you think of it. The saddle is a rest stop, not a parking place.)

As you progress, you'll find that you turn your handlebars less and less and steer with the insides of your thighs against the seat. You'll find that after a long ride, your nether area is much less sore.

Oh and you'll find you keep your ankles (and your wrists) much more flexible. So much of your "lightness" and your control comes from letting the bike (as described) kind of float under you.

I too got better with it (you never master this kind of thing, just improve) MTBing -- especially riding single track. If you think about it, that makes sense. If you are riding through trees, you can't be steering your bike where you want to go all the time. You have to, at some point, let your senses and instincts take over.

There is a sense of grace to it all to.

OK, my mystic moment is over.
