What is GST-Green First

Rust shield protection chain

Where low maintenance load demands the upgrade protective chain, the GST anti-rust protection chain works to be the bike’s best companion.


GST Technology is a unique range of eco-coating developed exclusively by TAYA and unrivalled in the industry.

  • Excellent corrosion protection for chains and other parts including bolts – up to 25 years of rust resistance!
  • With its hardened anti-graffiti surface, just water spraying to shed mud and debris off the chain at ease cleaning.
  • Smoother shifting because the coating is “baked-in” to the chain – it doesn’t add to the chain’s weight or thickness
  • Environmentally green – the manufacturing process does not use toxic chemicals or processes.

What is DHT Diamond Hard Tech

Non-Negotiable Durability

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.

DHT allows TAYA high-end products to compare with the branded chain products in the market with splendid performance in durability.

• Surface hardness improved by up to 25% (over HK1800)

• Increase thicker hardened layer by  doubled at least

• Minimize the wear of the gear group
