The "Nobby Nic" is also equipped with a "SnakeSkin", which protects it from lateral injuries. Its weight is 645 grams. At 520 grams, the "Rocket Ron" is a lightweight tire specially designed for competition. Finally, Schwalbe is presenting a snow-white Rocket Ron in a limited edition for all color-conscious riders. However, this will only be available in the classic 26-inch size.
