Review on Circuit Performance Aluminum Valve Stem by Richard Miller

Good news: you look good. Bad news: after a few months they fused to my valve stems. I've tried penetrating lube and twisting with pliers to no avail. Despite the aesthetics, this is an absolutely horrible design as the metals are not intended to be used together for any practical purpose such as: B. in the tires of your car. Throw them out once I remove them and probably replace old valve stems with them.
