Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Presta valve cores.

Presta valve cores.

Need some, as my sealant tends to get them gummy.

These look really inexpensive. Any experience with cheapo cores? Any suggestions?

These are Vittoria, and also really cheap, but seems they dont ship.

I googled "Vittoria valve cores" and got lots of options, including Amazon. I would copy and paste a few but I'm not sure what sellers would suit you if you are in India.

Not really what you're asking but I have no problem cleaning the lower o-ring by rubbing it for a few seconds with my fingers.

Yeah, I've cleaned them myself, too. I don't know about other sealants, but Orange Seal is pretty easy to peel when dry, so even if it's in the valve tube, enough will come out to allow the pin to move freely.

I source a couple of 10 packs every now and then and keep them on hand at races for just this reason. There's a group out there that has a killer new sealant injection system that includes a new valve design that should help cores keep from fouling. i am looking forward to testing it as trying to set pressures in the 20-24psi range for cross when it's cold and raining and sealant has plugged it is immensely annoying.

Oh and FWIW - you can clear the extension if needed with a safety pin at a race. they fit perfectly and can get to the bottom of a 50mm extender.
