Calvin Jones, head honcho of education for Park Tool Company in Utah, teaches us just how to inspect the ride-worthiness of a bike without any tools. Even if you don’t have any knowledge of actually fixing anything on a bike, he shows what to look for so that you can at least help your local bike shop mechanic with diagnosis and repair.
I’ve been following Park Tool’s YouTube channel for a couple years now, especially their Tech Tuesdays series. They’re all worth a quick viewing.
