Easy replacement

This was an easy and cheap replacement on a Michelin tube. I must have bent the end of the old core with the pump (would still hold air but made pump attachment difficult). The old one was easy to remove by hand and this was easy to install by hand. Functions as good as the old core.

Solid valve cores

My experience with these valves has generally been good.You need to be careful with them so they don't get slightly bent or "crooked."

So far this has worked fabulous.

I have broken off a few valves over the years and it works well just to replace the valve stem rather than the entire tube. I also have started to use tubeless tires on my gravel bike and these work well to replace the old valve stems.

Good to Have on Hand

I ordered these as a "have on hand/just in case" and not more than 2 weeks later I needed to replace the valve core as the original one became clogged with sealant. Way cheap insurance to get you back on the road!

It's a valve core, it does it's job. Eventually, they can seize up and need replacement.

Presta Core for tubeless applications

When you run tubeless with sealant you're eventually gonna get some gunky buildup and small leaks from the valve core. Always good to have an extra laying around when you need it.

Stan's Replacement Presta Valve Core is far superior to other brands. It is extremely well made.

It's worth it to pay a little more for Stan's Replacement Presta Valve Core. They are made much better (stronger, better materials) than other brands.
