In this live stream we talk with Ron/Ultraromance and Patrick about why they started Ultradynamico tires. Long time friends and self-professed tire nerds, they tell us about how they sold off Amgen stock to fund their first run of tires, what the tire designing process was like and what it was like to visit the Panaracer factory in Japan. If you love tires and are fascinated about small bike businesses in the internet age, this vidoe is for you!
