The whole purpose of the trackstand is to secure yourself in a stable position so that you can look around, breath, or rest your arms, while staying on the bike even in the middle of a zone.
Vincent Hermance lodges his front wheel into a recess.
There is the free trackstand before zone entry, and the locked trackstand with the front wheel pushing against an obstacle in the zone.Move your hips away from the bar turn.
It is usually easier to hold a trackstand position with your good foot forward, leaning over your driving pedal while turning your bars on the side of your bad foot. So find out what is your most comfortable foot forward, by pedaling up a slope and letting the bike stop. Your foot forward when you stop should be your natural foot forward (also for pedal kicks etc..)Practise riding up a slight slope.
If you lose balance on the side you turned the bars, turn the bars a bit more towards the slope, leaning the front wheel more into the slope while shifting your weight in the opposite direction. If you lose balance on the side of your driving foot, try to lean more over the bike, tucking your knees over the frame.Feel the pressure on the pedals - in a slope
1° Ride up a slope very slowly at an approximate angle of 45°, reduce your pace until the bike actually stops.
2° Turn the bars up against the slope and keep some pressure on your strong foot to stop the bike from going backwards.
3° Lean well over the handlebars and shift your hips away from the front wheel, realigning your body to face the front wheel direction.
4° If you lose balance on the inside of the turn, then turn more, leaning the bike a bit more into the slope, pushing yourself away from the frame.
5° If you lose balance on the opposite side of the turn, then straighten the bars and readjust your centre of gravity to lean nearer the top tube, tucking your knees over it.
6° Once you have stopped the off-balance movement to a standstill, try to find a comfortable middle position where you don't have to stretch or tuck too much.
Try both sides
Without a slope, you will have to use the brakes to a full stop, use the front brake to stabilize the bike,
then decide a direction in which to turn the bars. If you turn the handlebars to the left, lean on the right side of the top tube
(this is usually the easiest trackstand position for riders with the right foot forward).
With both brakes locked, you'll realise that you have two solid points of contact with the ground. Then you must constantly adjust your position
to find the perfect balance over the line between these two points of contact.
The more you turn the bars, the more movement you have to counter-balance and lean on the other side
(the front tyre contact on the ground moves as you roll the wheel, even when the brakes are locked).
Balancing on sloppy terrain
Lean up against the slope to secure some support.
Don't face down the slope, the front wheel rolls too easily.
With practise, you'll be able to maintain a trackstand turning the bars in any direction, change your front foot, and even change from one trackstand position to the opposite in order to get the best angle and support from the ground.
