We are Bob and Brennan, and we are into a very cool, very slick sport: ice biking! Our school holds an annual ice bike race, and goal is to design and build the winning bike. We know we want to modify one of last year's top models by adding studs to the tires. The studs will give us traction, kind of like cleats do on shoes. Our DragonflyTV question is: How many studs should we add for maximum speed on ice?
