Introducing our new Architectura™ Design, a patented innovation that takes carbon rim technology to new heights. Inspired by the awe-inspiring architecture of ancient Chinese bridges, this design transcends traditional limits to deliver unmatched impact resistance and durability. By strategically integrating pillars and arches into the rim structure, we have redefined how carbon rims perform under extreme conditions.

The innovative design effectively distributes and dissipates forces, mitigating the risk of damage and failure even in the harshest riding scenarios. Rigorous testing has demonstrated that carbon rims equipped with our Architectura™ Design offer over 30% greater impact resistance compared to rims of similar weight.

29ER 42mm plus wide trail Graphene disc brake mtb carbon bike rims

For carbon composite products, the normal epoxy resin system only supplies 5% strength contribution. The main function of resin is for molding and curing. With Graphene nanomesh filling technology, the resin system’s strength could be raised by about 20%. It means to a carbon part with a certain weight, we can make it the same strength&less weight or the same weight&more strength.

WSD series is water drop designed carbon rims, MBD930XC is arch bridge carbon rim only, both WSD and MBD series are new offset XC and Trail bicycle rims 2022.

What kind of Finish do you want on your mtb carbon rims?

We are a manufacturer of carbon rims, now we produce carbon rims with UD, 3K, 12K, and Satin UnidirectionalCarbon fiber. All UD, 3K, and 12K are the specified carbon weave pattern. 3K means there are 3,000 filaments per “tow”, 12K means 12,000 filaments and UD means unidirectional (no pattern). Satin Unidirectional Carbon finish is UD weave pattern with a free painting process, which is friendly to the environment, now more and more brands are using Satin Unidirectional carbon rims to end consumers. As for physical properties, UD is the strongest, then 12K, and the last is 3K.
