I have a 650b 2.0 tire. Will this tube fit my size? Which one should i choose?

Hello, The 650b means that you own a wheel of 27.5" in diameter. The other measurement symbolizes the width of the tire. We recommend you buy the Presta 27.5" X 1-75/2.125 inner tube size. This will cover both your diameter and tire width. Thank you, Ultraverse Team

Do the presta valves have removable cores?

No. The cores cannot be removed. They have a small part that unscrews to add air, but they do not come off.

Is presta stem removable?

No, it is fused to the tube. If you want Schrader, there are adapters.
