These Presta valves for my tubeless mnt bike tires work and look great. Kit has the needed items to setup. Fit and finish is nice. Everything went together fine and works well holding air. Good price as well. Most important, they look cooler than Schrader valves.

Whether you're just converting to tubeless or maintaining and need to replace a stem, these are a good set. In fact, they're a bit overkill: the included schrader adapters are just sitting in my extras bin. The airflow through the stem without the valve core is sufficient for readily seating even stubborn beads, and the inclusion of an extra set of plastic dust covers is appreciated. They'd have a perfect set if, instead of the special core tool, they took a hint from other manufacturers and built the core wrench into the metal dust cap.

My rims are designed for tubeless tires/bales but I’ve only used tubes. Got these to try it out. They do work well with no leaks…until you get a puncture. I know this is the same as a tube but the difference is once you have a hole in the tire you loose pressure. With a tube you can have a hole in the tire and the tube can still hold air. Almost a double layer of protection. Tubeless is probably better for some people but I think I’m going back to tubes.

Can't complain! Sealed up tight, no bubbles with the sealant like some others have done to me, seem to be exactly the same as a big brand, so I vote yes, give them a try. Make sure you measure your rim depth, don't just guess, you won't be able to get your pump on (unless you get the long ones, but then your friends will tease you).

I'll be totally straight with you: I ordered these specifically for the Presta-to-Schrader valve adapters, and nothing else. They were a good deal for the two, and I considered the valve stems a nice bonus, because I do have a mountain bike with tubeless tires. However, I've never installed a tubeless valve in my life, so I can't really tell you about the quality of them. What I can say is that the Presta adapters work perfectly, the o-rings seal up nicely and they don't leak a bit. These were necessary for me to be able to use my portable battery-powered tire inflator on my mountain bike. Saves me from buying a separate bike pump, since I already have the tire inflator which I keep in my trunk for emergencies. It also lets me use my regular schrader-style tire pressure gauges, of which I have very many. I've been into cars for many years, but cycling is kind of a new thing for me and these prevent me from having to buy quite a bit of new equipment.That being said, the included Presta valves do appear to be of good quality and I'm sure if I need them someday, they'll work out just fine.

I had some pretty long presta valve stems on my mtb just due to that being what was available at the time, so I grabbed these as they were shorter, and the red color matched well with my bike frame. Threw these on and filled the tires up, and they work great! They come with some o-rings, which makes them much easier to seal than the ones I had on there. They also come with a few bonuses, like some extra cores and some adapters, so for half the price of something you'd find at a local bike store, I love these things!

These valves have a nice, sturdy feel to them and they installed with no issues. Great value!
