Currently, I have 4 tubeless valves installed and in use on all the bikes I own.
However, there are no wheels currently equipped with Presta valves.
What does this mean?
To be precise, it's a tubeless system, but it doesn't use Presta valves.
Even as tubeless becomes more widespread, valves are still predominantly Presta valves.
They've been around for a long time, so they're not likely to disappear overnight. However, along with the drawbacks of Presta valves, there's also the issue that sealant and Presta valves don't mix well in tubeless systems.
Incidentally, besides (Presta, Dunlop, Schrader) valves, there's also the Regina Valve - but
made with an overly Italian gay sensibility it hasn't become widespread.
