Setup, Compatibility & Care

  1. Compatibility: This inner tube is designed for 26" wheels and compatible with tire widths from 25.4mm to 38.1mm. Ensure your tire size matches these specifications before installation.
  2. Valve Type: This tube uses a Presta valve. Ensure your pump is compatible with this valve type, or have an adapter on hand.
  3. Installation: Carefully insert the tube into the tire, ensuring it is not twisted or pinched. Partially inflate the tube to give it shape before installing the tire onto the rim. Avoid over-inflating during installation to prevent damage.
  4. Inflation: Inflate the tire to the recommended pressure indicated on the tire sidewall. Use a pump with a pressure gauge for accuracy.
  5. Care: Regularly check tire pressure before each ride. Inspect the tube for any cuts, abrasions, or damage, especially after riding on rough terrain. Store spare tubes in a cool, dry place away from sunlight.
  6. Maintenance: Occasionally, check the valve for any leaks. Tighten the valve core if necessary. Replace the tube if it develops leaks or significant wear and tear.
