The JT Sprockets JTA210.50BLK sprocket is a transmission part dedicated to off-road and roadster practices. Machined from aerospace-grade 7075-T6 aluminum (Ergal), it features an ultra-lightweight construction designed to minimize unsprung mass while maintaining good mechanical strength.
The mud-resistant geometry helps reduce the accumulation of dirt and mud between the teeth, thus limiting snagging and fouling of the final drive. Its Ergal design ensures a good balance between lightness and robustness for competition or demanding rides.
