We’re always listing to our riders feedback, and one thing we heard a lot was that the long valve stems necessary for deep rims cause the wheels to be unbalanced. The weight of the valve makes one side of the rim heavier and causes vibration and instability at high speeds.
To fix this we’ve added Carbon Valve Balance into every rim.
When we are initially laying up the carbon for the rim, we include two additional pieces of carbon on the opposite side of the rim from the valve (See the Red in the Image). We add a different mass of valve balance for each rim to balance out the length of valve you’ll need for that model.
Carbon Valve Balance is included in all Epic and Elite wheels.
