I think a more germane question than "How do YOU trackstand" would be "HOW do you trackstand?" I've never been able to figure this out on a bike with a freehub.
OK. This is how I trackstand, and this works for me, might not work for you but you asked.
First, be loose. If you're tight and stiff, you're shot before you start
Second; find your sweet foot - mine is my left [I'm a goofy foot surfer/skater so it's left foot forward] you might by a natural foot so it's right foot forward. You gotta find the sweet foot.
SMOOTHNESS is the KEY here; Gentle on the controls, fine adjustments.
Now when you're coming to a stop, change gears to a gear that you can get ontop of quickly[not grannies gear, but not a gear you'll need Landis Lollies to turn], just in case you need to take off in a hurry and this will help in 'the stand' because you should be able to use the torque of the gear to assist with the balance of 'the stand'.
As you come to a stop[not as you stop slightly before] transfer your weight over towards the front of the bike slightly [don't throw your hips at the riser] at the same time bring your sweet foot to the 2 o'clock position. Brake. As you stop transfer your weight back over the Bottom Braket. You should be at a standstill now. Cock the front wheel to a 45 degree angle in oppostion to your sweet foot. If you're right foot forward the back of the front wheel should be angled to the left. This way you won't hit your wheel and foot, thus assisting with 'the stand'.
While standing, slightly rock back and forth on the sweet pedal, if you're at 2 o'clock, rock back and forth half way between 1 and 2 o'clock - it will help with balancing against the torque of the gear, the frame, the brake and the front wheel.
Feather the front brake to assist in giving you a point to balance against.
Adjust the angle of the front wheel at the same time as the feather of the front brake.
So to summarise.
Slow down - relax your knees and arms HEAD UP - gear change - weight forward - 2 o'clock on the sweetpedal - stop - weight tranfers back over bottom bracket - angle front wheel so that rear is away from sweetfoot - feather front brake - slight adjust front wheel as needed - rock back and forth on sweet foot between 1 and 2 o'clock.
REMEMBER YOU'RE NOT GOING TO STAND THERE PERFECTLY STILL IN A TRACK STAND YOU'RE GOING TO NEED TO ADJUST EVERYTHING CONSTANTLY OR YOU'LL FALL ON YOUR BUTT. BE SMOOTH, BE GENTLE..
I always used to practise at home in the house with sneakers on. This help with 'the bail'
DO NOT ATTEMPT TO LEARN CLIPPED!
Also - if you cock up real bad and have to you can backpedal to bring your none sweetfoot around to 2 o'clock to catch a fall - this takes skills but can be done.
I have no idea how you would track stand sitting on the saddle. Also, try not to watch what your doing. Feel it. If you have your head down your body will naturally follow your chin, so you'll come unstuck every time. Remember, Head up, use the force, feel the stand.
