Tools Needed

- Screwdriver

Step-by-Step Instructions
Step 1: Remove the Tire
Before you can begin to work on your Presta valve, you will need to remove the tire from your bike. To do this, use your tire levers to pry the tire off the rim. Be careful not to damage the tube as you do this, as it can be easy to puncture the tube with the levers. Once the tire is off, you can begin to work on the Presta valve.
Step 2: Remove the Cap
Once the tire is off, you can begin to work on the Presta valve. First, use a screwdriver to remove the cap from the valve. Be careful not to lose the cap, as it may be difficult to find a suitable replacement.
Step 3: Remove the Valve Core
Once the cap is off, use your needle nose pliers to remove the valve core from the valve. This will allow you to replace the broken valve with a new one.
Step 4: Insert the New Valve
Once the old valve is removed, you can insert the new valve. Make sure that it is secure and that the O-ring is in place. You may need to use your pliers to secure the valve in place.
Step 5: Reinstall the Cap
Once the new valve is in place, you will need to reinstall the cap. Make sure that it is securely in place, as this will help to ensure that the valve does not leak.
Step 6: Reinstall the Tire
Once the cap is securely in place, you can reinstall the tire. Make sure that the valve is centered on the rim, and that the tube is not pinched or damaged in any way. Once the tire is on, you can inflate it and your Presta valve is fixed!
