In the production process of every carbon fiber wheel, there will be various tests, from the test of raw materials to the test before the final product is shipped to ensure product quality and superior performance. The final link is the test of the finished product. A comprehensive test is carried out on the finished carbon fiber rim, including braking problems encountered during the simulation of the riding process, and the stability, strength, torque and tension of the wheel set will be corresponding. Test. Ensure that guests have a good sense of experience and safety during the riding process.
