Interesting alternative for Presta!
I broke so many Presta stems.

Note on aluminum caps, they tent to corrode (galvanic corrosion) on salty roads in winter.

I have my next set of presta cores ready but these are neat. I have trouble seating tubeless even without any core so no help there, but seems awesome for day to day. I bent a lot of pins with bad pumps.

Been strongly considering these for my bike.

Looks like a dry herb vape I used to use.
