Notubes AS0015 Core Remover Tool Red

Great item and fast shipping

The standard. Buy at least three, you'll probably loose one, keep one in your pack and one in the garage. Works great.

It's small enough to fit into a patch kit, and it works great for all your valve-core screwing and unscrewing needs.So...why would anyone want to screw or unscrew a bicycle tube valve core, anyway? My comments below are all about Presta valves as I haven't had Schrader in years and am not qualified to comment on them.First of all, this gadget is only useful to you if you use Presta tubes, such as Continental Road Bike Light Tube, which have removable cores. Removable cores are supposedly less common for Presta valves, but they are more common at the handful of bike stores I visit. Anyway, here are the two reasons I use this tool:1. Presta valve cores can sometimes snap if you are a little too rough with your pump, or even sometimes if it's already weakened, going over a big pothole while riding. When they snap, you can imagine what happens: WHOOSH. Normally, you have to replace the whole tube. With this little tool (presuming you are using tubes with removable cores) all you need to do is unscrew the old one and screw in a new one and pump it up. You're on the road! (Valve cores are inexpensive: Stan's NoTubes Extra Tubeless Valve Core)2. If you use a pump that screws on to the valve, such as the Lezyne line of pumps, including Lezyne Alloy Floor Drive Pump and Lezyne Pressure Drive Hand Pump, the process of unscrewing the pump can occasionally pull out your valve core. Again, WHOOOSH. This little tool makes it a simple matter to either tighten your core before pumping, preventing the problem. Or if it happens anyway, just screw the core back in.FYI, Lezyne recommends adding Loctite to removable valve cores to prevent this problem. I suppose if you do that you don't need the wrench. I haven't tried Loctite yet, but it seems like a pain compared with using this little gizmo, especially since you have to redo it every time you get a flat and change your tube. I also like that by leaving the cores removable I can replace them on the go if they do snap. Anyone have experience with using just a little bit of Loctite so the core is less prone to coming out accidentally but you can still get it out if you need to?

Does exactly what it says, effortlessly. For the price, just get it. Tiny and fits in any bike bag too.

High quality tool for both presta and schrader valves. Not sure if I will carry it on rides since there are those little presta caps with integrated valve wrenches and no reason to carry around this "big" tool. It will live in my shop box.

Indespensible especially as I now have two bikes with tubeless tires. I find I need to top up and replace the sealant every 4 to 6 months especially in our hot summers as it dries out. So these are well made and the red color makes it easy to find in my tool box.

Makes the task of adding sealant to tubeless tires very easy.

Stans is known for tire products. This does the job - easily removes and tightens valve cores. Light weight but well built. Cool color as well. All pros, no cons.
