On Thursday night at 6:30 PM, Dan from the Bicycle Authority will be hosting a Flat Tire Repair Clinic at the Comma Coffee courtyard. Learn how to change a tube, one of the most important repair tasks that will keep your bike running. Learn how to patch a punctured tube. Most punctures only need a simple patch. Save your money! Don’t throw away those perfectly good tubes. Bring your flat tires and punctured tubes down for some hands-on training.
