EK/PBR 420SR Chain Kit 11/51 - Ultra-Light Sprocket
Designed for urban small displacement bikes and light enduro, this EK CHAIN kit combines a 420 SR chain with an 11-tooth sprocket and an ultra-light 51-tooth aluminum sprocket. The SR series benefits from a specific heat treatment of the plates to maintain the chain's flexibility even after prolonged use and to improve wear resistance.
Ideal for riders who want a final drive that emphasizes lightness without sacrificing maneuverability in urban environments. Regular adjustment and lubrication are recommended to ensure proper tension and optimal longevity. Manufacturer reference: Not provided.
