Material Advantages

Carbon fiber has been used on bicycles as a high-tech material for the last ten years. Carbon fiber is not strictly a carbon element, but a mixture of carbon elements that are braided and bonded and reinforced by epoxy resin.Carbon fiber is a new type of composite material, which has the advantages of light weight, high specific strength, high specific stiffness, and can be designed and molded easily, thus making the designed structure more efficient.


Super light Weight

T700:The standard XC/AM/DH version were constructed Premium Toray T700 Carbon fiber.

T700+T800 component:The super light series EIE carbon rim were constructed with properly component of Toray T700+T800.We cut the material size of the nipple bead area and strengthen the key parts of spokes to maintain the strength of the overall carbon rims.


Angled hole

The spoke hole angle design of the rim is very important , but its design angle range is limited . If the design does not match the design of the spoke hole angle of the hub , the bending phenomenon of the spoke can be generated .When our EIE carbon rims drill angled holes, the spacing and angle of each hole are calculated accurately to ensure that when the rim is connected to the drum through the stripes, no additional pressure is generated around the rim hole



The layer-up of each carbon rim is carefully designed, repeated tests and then determine final standards document. After that,we’ll send it to our layer up workers, who operate according to the operating standards. They cut the size of the material according to the layer- up instructions to produce materials for any part that can be used to increase the strength of the side part of the wheel set, to fit the grooves of the rims, to enhance the impact resistance of the wheels.


Tubeless Compatible

The rim was designed for tubeless compatible that means It is suitable for tubeless tires. This makes it greatly possible to reduce overall bike weight while improving cycling performance.


High TG Braking surface

The material is a combination of high temperature resistant epoxy resin and carbon fiber.It has excellent heat resistance and the highest test temperature values can be up to 250 degrees Celsius.In general,the maximum of rim TG resin can only reach 180 degrees when biking at high speed.
