EK/PBR 520MRD7 13/48 Chain Kit - ultra-light sprocket by EK CHAIN: a kit designed for Cross use, aimed at riders seeking lightness and reliability on aggressive terrains. This 13/48 kit (13-tooth sprocket / 48-tooth sprocket) combines a 520 chain with an ultra-light aluminum sprocket, offering a useful compromise between reduced weight and the durability expected from an off-road machine.

Designed to minimize friction while maintaining good tensile strength and abrasion resistance, this configuration is aimed at Cross riders looking to reduce unsprung weight without compromising the chain. Compatible with models such as HM CRE-F 450 R (2012, 2013, 2014), it fits common transmission settings in competition and training.
For optimal longevity, regularly check the tension, lubricate according to manufacturer recommendations, and replace the sprocket-chain-sprocket set when wear becomes visible. This EK CHAIN kit is a serious option for those looking to lighten their machine while maintaining the standards of a 520 transmission dedicated to Cross.
