Did you ever imagine that there was a real risk, when you pumped up your road tubeless setup to your tire’s max PSI, that you could delaminate your carbon rim? Well, ENVE explains how an imperfect (and quite common) tubeless setup can actually pressurize the internal cavity of your rim, exposing it to high internal pressures that rims, especially lightweight carbon rims, were never designed to handle. So they made these unique little Pressure Relief Valve Nuts as a simple, low-cost solution to safeguard your wheels.
And not just their wheels, they’ll work on any brand rims. Because the problem isn’t specific to their rims. Actually, it’s not a problem with any brands’ rims per se, it’s all about the set up.
