PBR rear sprockets set the benchmark for lightness and strength. Featuring a new and carefully designed pattern of lightening holes, they are available in iron, C45 steel or Ergal, and are made on CNC machines that make the machining particularly accurate and flawless, to the benefit of reliability, which reaches levels never achieved before. These sprockets are available in various sizes and colors, to be matched with the range of PBR front sprockets for 2-stroke and 4-stroke street, enduro and motocross bikes. The PBR rear sprocket line for street bikes has also been expanded with the induction-hardened C45 steel version, available for the most popular sport models. This treatment, applied to the entire tooth area, makes the part in contact with the chain even more resistant, ensuring the best reliability and even longer mileage. So if you are looking for a quality, durable product that doesn't cost a fortune, PBR rear sprockets may be the right answer.
