Is there any way to setup a Vittoria Corsa Evo CX tubie with removable valve cores?

They have that removable valve STEM that appear to have different threads at the base of the tubie than the regular presta threads. I added a Vittoria extension between the tubie and red valve stem prior to initial mounting.

I would like to change this setup so I can get some Stan's in the tire, but need removable cores. Because the threads at the base of the tubie are different I'm not seeing an obvious way to do this. If someone has done this, can you point me in the direction of the proper parts to purchase?

Not sure if I am getting it,
but the red valve is removeable;

the presta part on top of the red valve is removeable;


So you can extend them or put on another (longer or shorter) valve.

The valve core on the red valve stem is not removable.

de zwarten - yes, that is the exact setup I have.

duke249 - exactly. That is the problem!

Kinda crappy when you think about it. Everything in cycling is going to proprietary integration, including tubular tires! The only way to do it is to install the stans when the tire is off the rim, install the valve stem and then install the tire. For as nice as Vittorias are, the hassle of dealing with these valve stems is not worth it compared to a tire with a removable valve core and the silver Vittoria valve extenders.

a note on the silver Vittoria valve extenders: If you do use these, BE SURE to take the little black wrench in your saddle bag so when you get a flat and need to do a roadside change, you can remove the valve extender from the flat tire and install it on your spare. And also make sure your spare has a removable valve core.

I use these.

you can use the continental valve extenders with the removable core by just flipping them the other way

That is the solution I am looking for. Thank you!

Hi,

So Maxxis modular valve system is the same as Vittoria's then?
I take it the Maxxis extenders screw right onto the stub of the Vitto tub and also sport a removable core? Neat.

Ciao,
