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.

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!

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.

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

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.
