    I thought the same as you until I discovered the amount of clearance in the holes and how much radial runout they had!

    Hahaha, some of us don't have those fancy floating disks...

    Measuring is a good habit ;-)

    I don't have a full blown case, far from it in fact, but some things just need to be right!

    Great thread, imagine if was 'what tyre', instead of 'balancing tyres'?

    It's a nice sandpit to play in :-)

    Here be a static wheel balancer.

    Anything else is not static.

    Static=pertaining to or characterized by a fixed or stationary condition. showing little or no change: a static concept; a static relationship.

    Rotating is patently not static. As I said you are just manualy doing what the wiz bang machine does

    BD7ADF35-0820-4147-96EA-956AB21F90AC.jpeg I change my own tyres and balance wheel with rim locks adding stick on weights inside the rim then tape on.
    Lastly I fit the tyre and balance again.
    All this with static balancer I made.
    Bike runs straight, true and front wheel or bike doesn’t shake at low or high speeds.
    I assume that my machine is doing it accurately enough.

    Your rotating the wheel yeah?

    Here ya go, how about calling it a manual balancer? Cause static it aint.

    I don't balance wheels alone, my thought experiment says that adding 100 grams to balance a wheel, and another 100 to balance the complete assembly equals a 200 gram heavier wheel and tyre assembly. Just numbers as an example.
    In the majority of cases just moving the tyre relatively on the rim would balance the lot 200 grams lighter.
    However it is probably better to start with a balanced wheel if you are not able to balance unexpected tyre changes, ie. on the trail, patching etc.

    Not if its spinning, that's a form of static balancer, does it have a bearing under the top, can the wheel rotate?
    Observations are taken when the wheel is static, that doesn't mean that the assembly is static at all times during the balancing procedure...

    It is at rest, yes the wheel can rotate, how about calling it gravity balanced?

    They are all one form or another of gravity balancer
    Static balancer puts the wheel in a horizontal plane and adds or removes weight until it balances exactly horizontally. But the wheel is NOT free to rotate.
    The one we all do is rotate the wheel in a vertical plane and add or remove weight until it does not show a heavy point returning to the bottom of the plane.
    Ya whiz bang 'dynamic' computer jobbie rotates the wheel in the vertical plane and uses sensors to work out where the heavy point is and how much weight to put opposite, still using gravity.

    Pretty much the exact same thing we are doing with our eyes. And a little trial and error. But at no time is the wheel not free to rotate therefore it is not and I mean NOT static. Look up the meaning of static. Means still, not moving.

    How do you measure 'horizontal' ?
    Get past the fact that it can rotate, and accept that when the heavy side stops down the assembly is static. Hence static balance, I would not trust a bubble in a circle just because it's a bubble in a circle anymore than I trust dynamic balancers. Gravity does not lie, your example of a static balancer relies on gravity, and an accurate bubble, or you could rotate it 180 and see if the same side is low, not static while you move it.

    Look up the definition of free to move, it does not automatically mean 'in continious motion'...

    So when you use the machine it spins then stops so you can add the required weight.
    By your definition that is a static balancer as well.
    If it moves it aint static. Simple fact. One use a machine to spin the wheel n one uses muscle power, same same
    And horizontal is horizontal is horizontal.
    You wont trust a bubble but you will ignore the friction in your so called static balancer that uses rotation to do its' job. Mind I'm not saying I'd use such a balancer either. Not because it is flawed just archaic
    Engaging in a battle of wits with the unarmed is boring.
    Nuf said n I'm out of this thread

    Muscle power to spin the balance, you must be on drugs. The wheel is free to move until it stops heavy side down, even on your definition of a static balancer. Static is stopped with the heavy side down, or off bubble or reliably with gravity, a dynamic balancer decides the balance while in motion, and indicates where to put weight according to degrees, oh and you have to turn the wheel assembly by hand to the beep to know where to place weight.
    Gravity works, a static balancer works when everything stops moving... able to move does not mean motion!

    I can only gather that you have never balanced a wheel assembly either static or dynamically.
