EK/PBR 428DEH 12/60-134 chain kit designed for urban riders seeking simple, reliable, and economical equipment for transmission. This kit includes a 12-tooth front sprocket, a standard 60-tooth rear sprocket, and a 134-link chain with a pitch of 428, ready to be mounted on compatible chassis.
Ideal for small displacement bikes and urban use, this kit requires regular maintenance (tension and lubrication) due to the non-sealed chain.
