Bikepacking Fix-a-flat clinic

Bikepackers: Fix a flat clinic (for tires with tubes) This clinic is open to any Mountaineers members.

Strategies and techniques to limit the risks and to fix a flat on a bike with non-tubeless wheels. Bring your own bike and whatever tools & supplies you take along when you go riding (if you're comfortable taking off and putting back both front or rear wheel, you can just bring in a wheel.) The presentation will be followed by a hands-on session where you will get your hands dirty, and will experience the perils and tribulations of replacing a tube on very your own pride and joy. Dress for success (that is, be ready to get greasy. Shop apron and surgical gloves can come in handy.)


  • Understand the different parts of a wheel and tire, their functions, their names, as well as the various standards used for sizing tires and tubes.
  • Know what tools and spare parts are required to fix a flat tire.
  • Understand the common causes for flats, and the best practices to help prevent a flat.
  • Know and have practiced how to replace a tube to fix a flat tire.
  • Note:
    • this course is NOT aimed at users of tubeless tires, but it can still come in handy when facing a puncture that cannot be fixed, and one needs to use a tube;
    • the handout reviews how to patch a tube, but we will only practice this skill if there’s enough time left in the class.

Clinic with start promptly at 6:30, ends at 9:00.
