Items came as described. Neatly packaged with fast shipping. I’m happy with the quality and the valve caps look great on my specialized stumpjumper. It’s an easy way to remember to smile while you’re bombing down your favorite trail. Great gift idea. Don’t take life too seriously

How to Fix Stripped Threads

Love the caps but you must be careful not to over tighten. It is easy to strip the treads. Even though the instructions warn you not to over tighten, I screwed up a thread.. I took a small file and opened the area and the glued in a traditional cap. This was a simple fix to a stripped thread.

Thanks for the thoughtful review — and glad you’re enjoying the Astronaut.

We’re always refining the fit and durability as we continue producing these, and feedback like this helps us keep improving.
