How to Fix a Flat in 10 Minutes Flat

“Are there thorns over here?” Lorri asked as we rolled on the dirt and gravel paths criss-crossing the Guadalupe River Trail. We had peeled off the San Jose Bike Party Ladies Ride and were searching for the rose garden on our way back to the train. I felt like a kid again, exploring the trails along Bayou Duplantier with my best friend Molly. Except this time Lorri and I were in dresses and heels. Momma never let me play in my Sunday best.

“Mmm, maybe,” I replied. Our fear wasn’t so much thorns in the rose garden, but the dreaded goathead thorns that sneak onto the path to take down the burliest of bike tires. After meandering a bit, we found the rose garden, took some fashion photos, and made it almost all the way to the train station before Lorri’s tire went flat. We scurried onto the train where Lorri went to work repairing the tire while I offered moral support.

By the time we reached Sunnyvale she was done. The conductor was impressed: “You fixed it already?”

“I’m a pro,” Lorri replied matter-of-factly. As founder of Velo Girls bike club and racing teams 10 years ago, Lorri has changed more than her share of bike tires. She’s also founder and owner of Savvy Bike, which offers skills clinics, coaching and bike fit services that go far beyond a simple flat tire repair (class calendar).

Here’s how Lorri fixes a flat, adapted from her Bike Skills 002: Basic Bicycle Maintenance class. For more detailed instructions and for complicated fixes like a gash in the tire’s sidewall, read the long version.

Don’t forget to clean your hands when you’re done! I keep tissue-sized rag in my repair kit just for that. A squirt of water on the rag, a little rubbing, and I’m good until I can soap up in a washroom. Momma would approve.
