Continental Sprinter Tubular tires - Removable valve core?

I’ve just made the switch to tubular (yeah, I know from everyone about Rolling Resistance). I’d like to use the Tufo valve core extenders but am not sure if the valve is removable on Continental Sprinter tubular tires. They seem like such an easy way to avoid the hassle with the other extenders.

Thanks in advance.

yes they’re removable
.

Only the low, low end tubs have non-removable cores.

OK Thanks. So the Sprinter and Sprinter Gatorskins should have the removable valve core.
Cool.

Yeah, I don’t believe I have ever come across a Conti without a removable valve core. I think I only ran into a low, low end ($12) Clement that lacked such a thing.
