Developed through finite element analysis and rigorous real-world testing for engineered strength, TAYA’s 12-speed chain is packed with smart features that keep the chain running and shifting smoothly in the harshest riding conditions

TAYA ONZE-121 bike chain is designed for 12-Speed rear derailleur use. With the diamond-hard technology applied, TAYA brings up the durability into a new era.

"With Diamond Hard Tech one more revolutionary technology has been developed.

DHT provides the solidest hardened base with extreme hardness performance and self-lubrication feature.

To balance the durability of chain with other derailleur components is an essential task for derailleur parts makers. DHT hardened treatment does not affect the worn condition of cassettes and chainwheel and that friction-free lubrication helps shield away from the strain and wear on the drivetrain components.

Thanks to the excellent performance in anti-elongation, chain life has greatly increased based on the DHT advanced durability enhancing treatment.

DECA-101 refines perfection in both design and functionality. The sophisticated coating on the surface withholds the scratch-resistant and appealing appearance. DHT treatment applied also enhances durability and strength. Wherever you want to conquer, you can rely on it.

Perfect match on SRAM and Shimano 10-Speed MTB and Road derailleur system.

DHT provides a solid base to the chain, and the easily maintain feature keeps great shifting throughout the chain’s life. DHT hardened treatment is not The self-lubrication feature also prolongs the life of the other drive train components. And because the DHT treatment slows down chain elongation, chain life is greatly prolonged.
