 I'm wondering how do I fix this valve stem? I want to put air in the tire. But, i don't see the usual screw-on stem part. The other bicycle tire has such type of stem, so I am thinking this one is broken. How do I repair our replace it? Thanks for help, update: thanks for the helpful info. i plan to get some more time on this during this week. this evening, i found a part with my pump kit that i was able to screw on. it didn't work with one of my pumps, but i have another pump i plan to try on it.
