How to Distinguish the Weave Of Your Carbon Rim?
These days, we have got quite a few mails from customers. They are confused at our UD U-shaped 45mm clincher rims. They see 3k weave on rim bed and consider the rims are 3k, not UD actually.
Please check as below, then you will understand the rims are with UD construction.
For more detail information about 3k/12k/UD carbon fiber:
The 3k 12K UD carbon fiber weave for rim and frame
No matter 3k/12k/UD rims, all the inside carbon fiber are UD carbon fiber, UD layers are applied at different angle on each other. They are still not identical.
For example, the orientation are different( some are placed at 0 degree, some are 45 degree, 90 degree,etc.). It is very important to use right orientation for carbon layers. Our engineers will use experience & testing result to use the best orientation for each carbon layer to make the rims with best strength.
For 3k rims, it is only the top layer in 3k weave( only one layer 3K, all the inside are UD).
For 12K rims, it is the same. Only the top one layer is 12K weave.
For UD rims, it is around 99.9% carbon fiber layers are UD, only one small 3k layer on the top of rim bed, to prevent carbon fiber split after spoke holes machining on rim bed.

But there is one mechanical benefit for 3k woven carbon fiber. Putting the 3k woven carbon fiber around hole area& machining, it can prevent carbon fiber from laminating while machining. That is why 3k weave(only 1pcs small layer) on the top of rim bed.
And one 3k layer on the top of rim bed will make the rim looks special and nice.
So, our UD rims are not 3k construction, it is really UD rims 700C U-shaped.
Please contact us if there is any question of rim construction. We will let our engineers reply accordingly and share more detail Technology about U shape 45mm clincher. It will be better if customers help to offer some suggestion.
