Review on Corki Schrader Aluminum Bicycle Covers by Harley Franchetti

I was surprised to see how crappy these things are. They are very thin, made of very cheap aluminium. The casting is absolutely terrible and the anodizing isn't much better. The threads are rarely cut into the thin walls of these valve caps and they are very easy to thread on unevenly and difficult to thread on effectively due to the severe wobble on the threads. One of the caps was unthreaded on the inside. There is no rubber pad inside. They are also very deep so you have to screw them in forever to finally equalize them by hitting the rubber on the valve stem (it doesn't hit the cap that closes the valve). I will never buy them again and will most likely throw them away when I get a better set.
