700cLaufräder

700cLaufräder refers to a specific size of bicycle wheel, commonly found on road bikes and some touring or hybrid bicycles. The "700c" designation originates from an old French system of measurement where the "c" indicated a particular tire width within the 700mm nominal diameter. In modern ETRTO (European Tire and Rim Technical Organisation) standards, this wheel size corresponds to an ISO diameter of 622mm. This means the rim itself has an internal diameter of 622mm, and the tire size, when mounted, brings the overall diameter closer to 700mm.

These wheels are characterized by their relatively large diameter, which contributes to a smoother ride over rough surfaces and better rolling resistance compared to smaller wheel sizes. The 700c standard allows for a wide range of tire widths, from very narrow racing tires to wider, more robust touring or cyclocross tires, providing versatility for different cycling disciplines. Many modern bicycles, especially those designed for speed, efficiency, or long-distance riding, utilize 700c wheels. The availability of components and accessories for 700c wheels is extensive, making them a popular choice for both manufacturers and consumers.
