20 Pieces Presta Valve Core 4 Pieces Alloy Presta Valve Caps with Valve Core Remover Tool

Quality valves, great tool, excellent bang for your buck. I got these so I can carry spare valve stems in my saddlebag and for the tool.You wont be disappointed. These get the job done.

The cores work as well as the ones we have picked up at the bike shop. Great way to keep the tubeless set up going on your mountain bikes.

I've always been replacing tubes once I detected a leak. However, during the pandemic with tubes somewhat in short supply, I tried my hand at patching. First my kids bike tube. Then my neighbor's kids'. And for my bike, there was no leak on the tube itself. It was the valve. I suppose I'd been roughing it with my air pump and must've bent it out of shape. I didn't know what replaceable cores on tubes were (you should look up YouTube) but as soon as I found out, I checked to see if my tube was indeed 'core replaceable,' searched for and ordered this product.Replacement of valve on my 29er mountain bike took approximately 1.5 mins. Beats the 15 - 25 mins I typically spend replacing a tube. And these valves are very inexpensive.Good stuff. You should definitely look into the repair option. Because time, money and environment. Unless the tube is old or flat prone.

For the longest time it was common practice for me to replace an inner tube that would no longer accept air. The thought process was simple. I would get a flat, patch a tire, fill it with air, and then move on. When the tire would no longer accept air, it was time to replace the inner tube. That was the process and for a time it worked flawlessly. Then the pandemic happened and inner tubes became one of those essential items.The bike shops told me that they couldnt keep them in stock. The online retailers gave me unrealistic dates for arrival. Neighbors and friends only had used inner tubes. The online sellers (Ebay and Amazon) were not as reliable as the commercials would allow us to believe. I was dreading getting on the bike and having a puncture. The thought of replacing a tube that wouldnt accept air was something that I pedaled with daily. I rode as one would walk over cracked iced, carefully watching the road infront of me for any debris. Glass, sticks, garbage, toys, rocks, even the routinely found train nail or stray keychain would not be lost from my glance. I was watching everything.Then I happened across a video from youtube, that mentioned something about a valve core remover. I had no idea that it was possible to take the core of a valve from an innertube and replace it with a new one. What was more was that these valve cores were cheaper and easier to acquire than a brand new inner tube. I purchased this one and was surprised at how easy the process was. Simply taking the included valve core wrench, something I could never find in the bike shop, remove the old valve core and replace it with the new one. The whole process took less time then it took to type this review.I cant tell you how much money I have thrown away because I had valves that would just stop working. Either the air could not be pushed through them or they just became so filled with (whatever) that they just stopped working. Had I known about this, or products like this I would have save myself so much money. Now when i ride, I dont have to be as cautious. The thought of being stranded on the road, with a tube that wont accept air is a fear of the past. I keep the valve core wrench as well as the spare cores in my bag, just in case I need them. Granted I have only used it a few times and those times I was in the house. Still, I believe it is better to have the tools to get you back on the road, than to need them and not have them.

I usually use the rubber or plastic valve remover and it is such a pain. This Alloy Valve Core Remover Tool is amazing and I remove the valve with no issues. Worth it and highly recommended.

these are just what I needed , they work great ! the valve core that came with the tubeless stems were crap from the start! bent the screw head the very first time I had to put air in. the ones I ordered fit good and don't bend the screw valve head when putting air in them. highly recommend for tubless tires!

Great valves and valve core remover. I would recommend to anyone looking for one of these kits. Solid construction that will last a long time.

The wrench started to bend after a few uses. I wasn't entirely pleased with this product.
