HOW WE PREPARE THE FABRICS FOR LAMINATION

“It’s known that the circumference of a 700c or 29″” rim is around 2 meters long.”
Many manufacturers are dividing it into two pieces, that is, one piece around 1 meters long.
Then connect the two pieces together to become a rim circle.
Many factories do this for many years already.
Indeed, there are some very unperceptible problems.
For example, maybe, you have the experience that during wheel building,
There are always some spots not flat, especially, the edge along the bead.
Or during riding, riders always feel a remarkable rolling-weight-unbalance, especially, at higher speed.
The reason actually is because the manufacturers are preparing the fabric at least two pieces, some even more.
“So there are too many “”knots”” .”
Where the knots accumulate together, making some position over-weight, and over-thick.

After founding out this secrets, now we only prepare the fabrics in complete piece only.
So there would be only one knot one layer.
And our engineer could do just the knot position to control the weight balance and flatness.

HOW WE DO DRILLING

Drilling is also very important for wheel assembly and wheelset durability.

Bad drilling will get the incorrect angle, which makes pains for wheel-assembly.

The bad angle would also make a strain in the spokes and nipples, causing breaks.

Of course, this is a quite complicated issue indeed.

It would be related to the rim design, hub design, and could also improve by nipples.

For a rim manufacturer, we have to make sure the drilling angle is accurate and precise.
