Accidents are bound to happen. Learn how to quickly and safely change a flat tire and get back to having fun.
1. Diagnose the cause of the flat tire.
Some common causes are: Pinch flats in tubes, thorns, cut sidewalls, dented rims, and defective rim tape.
2. Uninstall the Wheel
Shift the gear to the hardest gear (smallest cog). This will make uninstalling the wheel easier. For modern Sram derailleurs, make sure to utilize the “Cage Lock” function. For modern Shimano derailleurs, make sure to disengage the clutch.
3. Remove the Tire
Force the bead of the tire to the center of the rim on both sides. This will make it easier to remove the tire and prevent damage to the rim tape.
4. Sweep inside of the tire for debris.
You want to ensure the inside of the tire is free of debris to prevent any damage during the installation of the tire.
5. Partially inflate the tube to prevent pinching the tube during install.
