And this technology can also help our rims to stand wear andtear,increase high-temperature resistant and brake force.Full Carbon Toray T700SCWithout saying,material is the most important for a rim.There are 3 main places producing carbon fiber material - Japan,Taiwan and China Mainland.Toray in Japan is the biggest and best carbon producer in the world,we use Toray T700SC from Toray for all of our rims.Although Toray product price are almost 2X than those from Taiwan and 3X than China Mainland,comparing the durability and stiffness it brings,it's definitely worth.We Make It Durable - 35 layers in spoke hole sideFor the spoke hole side,we use as many as 35 layers aiming to avoid cracking,the extra layers make the rims extremely stiff and durable.We Make It Strong - 9 layers bodyCarbon material is 8 times as strong as steel by weight,but is not so good at handling impact force.So we mix 9 layers of the carbon material in different angles, a mixture of different angles resemble a uniform material,and they make the rim body resistant to all kinds of forces.
