Svar fra SkatePro: I'm sorry to hear, they didn't last as long as you expected. The longevity of a wheel depends on several factors. Your riding style, if you use your wheels to break, the surface you're riding and actually also the weather conditions plays a role. When it's sunny and warm outside it affect the durability and hardness of the wheels.
