EK 420SRO O-Ring Chain 420 — Ref. 420SRO-STL 106 SKJ
Designed by EK CHAIN, this 420SRO is an O-Ring chain intended for urban, cross, and roadster uses. Its design combines heat-treated steels and optimized link perforation to reduce weight without sacrificing the assembly quality characteristic of EK. Ideal for setups requiring robustness and regular maintenance, it retains internal lubricant thanks to the O-Rings, limiting dirt penetration and slowing lip wear.
Installation and maintenance: check the correct alignment of the sprocket/crown and the tension before each ride, lubricate the seals, and replace the chain if the links show signs of elongation. Reference suitable for many cross models and small displacements.
