Are all Presta valve cores removable?
Unfortunately, in order to install it in a tube, a removable valve core is required. Some, but not all, Presta tubes have removable valve cores.
How do I know if my Presta valve has a removable core?
On a presta valve there is a wide threaded part that the lock ring attaches to. And a narrower part with the valve lock nut above it that the cap threads onto. If the narrow part has two flat sides to get a tool onto, then it’s removable.
How do you tighten a valve core?
How do you tighten a valve stem core?

- Hold the valve stem while you turn the valve tool clockwise onto the top of the valve stem.

Why are Presta valves so difficult?
The only time it has been difficult is when the valve stem was too short for the deep rims I have, so there was no enough stem for the pump head to clamp onto. Solution was to buy a valve extender. With my floor pump, you can easily tell when you have a good connection.
Is Presta valve better than Schrader?
Presta valves are easier to pump than Schrader, because they have no valve spring to overcome. In narrow rims, clincher tires also leave insufficient space between tire beads for larger Schrader valves. In contrast Schrader valves are more robust, universally used, and have an easily removable core.
