Enuma Chain (EK Chains) was founded near Komatsu on the west coast of Japan in 1941 as a general roller-chain manufacturer. In 1974 EK Chains introduced the world's first sealed O'ring chain which completely evolutionised the world of roller chains for higher quality, lower maintenance, improved longevity and a cleaner environment for a product which is typically lubricated by oil and grease. The lubrication which is essential, attracts dirt and debris and it usually gets flung off the chain as the sprockets turn at high speeds and oil ends up stuck all over everything which is close to the chain.

EK Chains have spent a lot of time and energy investing in maintaining quality management standards, they have been recognised and certified with ISO 9001 which reinforces the guarantee of safety and precision in every product they have on the market.

EK Chains obsession with technological breakthroughs have held them at the front of the pack with high quality performance which has built them a reputation throughout the racing industry as a top contender no matter what discipline you are competing in.
