40mm carbon rims

40mm is a very classic and scientifically reasonable height with strong comprehensive performance. Can be competent for climbing and can also play well in aerodynamics. our tubeless carbon rims are made from Premium Toray T700 carbon fiber + stable resin system, which is the basis for light weight. In addition, we optimize the lay-up design, eliminate excessive materials to save weight, and add extra materials around spoke hole area for reinforcement. Thus, our road carbon rims are light weight, but still strong and stiff. The lighter, more rigid wheels can accurately control the angle of entry when cornering at high speeds, and the wheels can react quickly when sprinting to help you win. - 40mm depth 700c carbon disc rim for road bike /Grave bike. -T700/T800 high modulus premium carbon fiber materials for light weight and high strength. -Asymmetric and Symmetric design optional. - Both rim brake and disc brake systems are available. - New bead lock system, better tire holding, prevent air leaking.
