Step 1: Check if your valve core is removable

Look closely at the top of your Presta valve:

• If you see two small flat edges, then yes, the core can be unscrewed.
• If there are no flat sides, the core is fixed and not removable.

Step 2: Deflate your tire completely

Unscrew the small valve pin and press down on the tip to let all the air out.

Step 3: Unscrew the valve core

• Place the wide end of your Presta valve core remover over the valve.
• Turn it counterclockwise.
• Once it’s loose, gently pull it out.
  

🔄 To re-install the valve core:
Insert the core back into the valve and screw it in securely using the core remover. Avoid overtightening.
