Not comfortable with how to change a flat tire? This is a great opportunity to learn how! Join us at Calumet Park, which is only 15 miles from downtown Chicago, for a free flat tire changing clinic. We will demonstrate how to do it first, but then you can practice on your own bike and using your own tools, while also getting some hands on assistance from Grit Endurance Coaches! The clinic starts at 10:30, but we will also be offering an optional brick workout opportunity before it! You can come to the workout beforehand or just to the clinic. All levels are welcome!
