Along with Tom's father, who was also a cyclist, Jobst was an important mentor for Tom - faithfully sharing his vast engineering wisdom while also actively influencing Tom's riding. Bound only to the thrill of experience and exploration, for decades Jobst's and Tom's tires rode over more than a few different surfaces on any given ride. It's these adventures with Jobst that helped inspire the Alpine JB tire. This unique bicycle tire is built to ride wherever your two-wheeled journeys may take you.
