Tubeless Schrader Valve - Alloy - Pair - Choose Color and Size (40mm or 46mm)

Good quality, sealed well. Replaceable valve stem (Good to have when seating the bead - necessary if you add sealant after mounting.) 40mm was plenty long for my 40mm x 29" rims. Like the others, it's made of aluminum, so be careful with the threads when you add air. A portable screw-on air pump won't work with stripped threads. Seems to have quality rubber seal and o-ring.

These are well-made, sturdy, don't leak, and of course any compressor or pump easily attaches. I can't believe I put up with Presta for so long on my mountain bike.

Hard to find color, love it. Too bad the caps don’t match. -1 star for one o-ring breaking prior to install. Luckily I had an assortment

Air goes in tire. Air stays in tire. Ride. Air still in tire. Ride again many times. Air still in tire. What else is there to say? Oh, one other thing, they are easy to fill since they are the same as the valves on car tires which are much simpler than the bike specific Presta valves. You have to make sure that it will fit in your rim though if it is drilled for smaller Presta valves. Oh, another thing. They have a removable core so no problem putting sealant in. Overall, couldn't really be better so far...

Están re chulas y lista para aguantar presión por uso prolongado Qué es lo mejor

I did a dry fit before putting in tubeless sealant. No matter how hard I tried to tighten it to the frame it leaked around the circumference. This stopped when the tubeless sealant started to work its magic. Also, this is not anodized and the colored finish comes off easily exposing the silver metal underneath. They've held up for 2 rides without any leaks so only time will tell but I'll probably spend more money on valves next time

So glad we are not stuck with fiddly little Presta valves to run tubeless on a MTB. Schraders are superior in every way, that’s why every car, truck and motorcycle uses them. These stems seal great, fill fast and look nice. And they’re half the price of a pair of Stan’s Presta stems. Drill your rims and never look back.

These valves seem to work well, and I was able to get them installed by a bike shop on my wheels. There's one issue though: the Schrader threads have a bit of a taper to them that makes it so it's hard to thread on an inflator and it loses an awful lot of air as you screw it in (it holds and inflates perfectly fine once you get it threaded on all the way). This was probably designed with an air chuck in mind, so it's worth knowing if you like to use a car pump on your tires, like I do.

Why Local bike shops don’t sell these is beyond my understanding. these are well constructed did not leak first time doing a tubeless install and it went quite well I use the muck off tubeless kit

Bonitas y excelente calidad

希望の色が欲しかった。

My wheel holds air again after 3 different presta valves failed due to damaged hole. Drilling a larger hole and using these not only solved my problem it allows for easy sealant transfer and pumps up faster with larger valve.

These worked as advertised to set up my son’s Specialized Hardrock as a tubeless rig. The stock tires don’t seal easily but the valve lets enough compressor flow through that the sealed up with no issues. Didn’t even have to removed the valve core. Pretty sweet!
