• 1.PROFESSIONAL VALVE CORE TOOL - Great install and remove tool that takes the guesswork out of tightening or removing the core in Presta tubes with removable cores. It also has fittings for Schader valves and a presta valve extension tool. Easily tighten or remove valve cores on bicycles, cars, and any other air filled tires.
  • 2.LIGHTWEIGHT AND PORTABLE - The valve core remover tool is multifunction portable tool, which weighs only 0.46oz, so it’s a must have in your saddle bag, great accessory for cycling enthusiasts.
  • 3.WARM TIPS - The valve core would back out when you would unscrew your lezyne pump and getting stuck, then you must realize that the valve core has problems and needs to be replaced.
  • 4.GIFT ACCESSORIES - The valve core will not cause problems for a long time, so the 2pcs presta and 4pcs schrader are enough for you to replace the valve core when there is a problem, which can save you unnecessary waste of money.
  • 5.MUST HAVE TOOL - you have been cycling for many years without this tool. you may have just lucked out all this time without needing it, But if you have it, you won’t be stuck on the road.

Until the recent purchase of a single-speed, 27 inch bike, I wasn't aware that Presta valves have removable cores like Schrader valves. Different styles, but the same concept. The single speed had a flat tire for what at the time was an unknown reason, but ultimately turned out to be because someone had removed the valve core. I went through my stock of needing-repair presta-valved tubes and found one with a salvageable core, managed to remove it with pliers, and got the tire inflated. It was definitely time to deal with no spare cores and no proper tool either. This kit did both and I'm now better equipped and happier, too.

Got this because I wanted to put Slime in some new tubes and the stems were really tight and destroyed the one that's included in the Slime cap and then a second empty Slime bottle I hadn't thrown away yet. This one worked great, took just enough force to break the plastic one included in the Slime cap so this one held up fine. I found out one of my bicycle multi tools has one but where it lives on the bike I use the most this one can just live on my bike stand so no money wasted. Really happy with this very basic tool.

Perfect little tool for putting in or removing valve cores in bicycle tires. Thank you very much!

it fits all my tube's and sizes I need.
