We have two ways to fill the hub, models F1 and F2. Some companies work by mixing these models and many times the company hires an employee who has experience with another model of machine and ends up with a little confusion during assembly. Mainly in terms of machine installation, where service engineers leave machines with factory standard settings. Mixtures in the filling model can cause problems of uncertainty in the correct size of the selected spokes, uncertainties in length and even uncertainties in nipple size. to avoid this here is this ideal example of how to fill the hubs. When we are teaching a rim model to the machine, it also needs to know this information, which is why it is very important to pay attention to this detail.
F1 Model :
The F1 filling model is also related to the type of rim hole which is also characterized in F1 and F2
pay attention to the position of the rim hole and the correct position to fill the hub
F2 Model:
observation:
It doesn't matter if you turn the rim upside down, the f1 model will always be f1 and the f2 model will always be f2
The rear hub
The rear hub has a peculiarity in that it is not symmetrical. We always need to mount the shorter spokes at the top and the longer spokes at the bottom.
Front Hub:
no size distinction needed. the same size spoke goes to both sides
