thanks for heads up on taking too much off.
I honestly have no idea if any of my tubes have removable presta cores, but ya, I can see how taking the adapter off could bring a removable core with it (never had that happen in all the years having an adapter on one wheel, and taking it off to use a regular presta pump)
