2pcs Presta to Schrader Brass Bike Bicycle Valve Adaptor with Seal Ring Adapter Converter

I never knew there was such a thing as a presta valve until I bought some tubes that had them. This screwed right on and allowed me to not swap my pump back and forth.

Exactly what I wanted, good build quality and helps when I want to use my air compressor to fill up my bike tires.

I purchased this pair for several months. It does whatever it is supposed to do perfectly! The only caution is that if you have yet to use a Presta adaptor before, you should google a YouTube video to learn how to use it.

I used as adapter from Dunlop to Schrader (normal valve). It works well, is just a bit hard to push air in but it works.

Screw them on and use a standard pump to inflate. Worked like a champ. Since there's 2, I put 1 in the bike bag and 1 in my garage. They screw on easily and I haven't had an issue filling up the Presta valve's.

I have three pumps, a handheld, a stand up and a power pump, and all three did not want to work to pump up my Schrader valves. Yes, I did have and I did use the plastic adapters that came with the pump, my handheld didn't even need adapters, it was made for Schrader valves, but boy did I always get frustrated when trying to pump up my bicycle tires. I tried 20-30 times to no avail. I was one Amazon short of putting my head down, leave my balls in the garage and bringing my bike to the shop and ask them to pump up my tires. But this order of the brass Schrader adapters solved all my problems. I got them in the mail, I took off the valve cap, unscrewed the little screwy thing on the valve, "burped" the valve, screwed those little brass babies on, screwed on my power pump and BAM!, it worked. I was able to easily pump up my tires and I do not feel like a complete failure anymore. Manhood restored, I'm walking upright again and flipped off the bike shop next time I drove by. So if you feel like a complete idiot when you are trying to pump up your Schrader valves with those plastic adapters, feel no more. Get the brass valve adapters and you will feel like you have brass balls.

This is the item I never knew I needed. I had no desire to have multiple pumps in my garage. When I realized the new tubes I bought had presta valves, I did a quick internet search and these came up. If this is your first time using these adapters, remember to open up the presta valves all the way before installing these. Happy trails!

This adapter will not screw on Presta valve stem when valve is removed. It is good only when valve is screwed on.
