EK 525 NX-Ring Super H/Duty Green Rivet Link

Meet the EK 525 NX-Ring Super H/Duty Green Rivet Link — a purpose-built replacement rivet link crafted to endure the rigors of serious riding. Built around EK’s NX-Ring concept and finished in a distinctive green, this link isn’t just a connector; it’s a performance upgrade designed to keep your EK 525 chain running smoother, longer, and with less maintenance in the harshest conditions.

Why the EK 525 NX-Ring Green Rivet Link stands out

• 
  NX-Ring sealing technology minimizes dirt ingress and locks lubrication in place, helping extend chain life and maintain crisp, consistent shifting in mud, dust, and water.
• 
  Heavy-duty construction with a robust rivet pin and reinforced plates designed specifically for the demands of the EK 525 chain, reducing wear on both the link and adjacent components.
• 
  High-visibility green finish makes inspection quick and easy during rides or maintenance, while also providing corrosion resistance in wet environments.
• 
  Precise, compatible dimensions engineered to mate perfectly with EK 525 chain links for a secure, gap-free connection that won’t compromise power transfer or derailments.
• 
  Tool-friendly installation compatible with standard chain tools, so you can replace or repair on the trail, in the workshop, or at the race site without extra adapters.

Ideal use cases

• Enduro and downhill riders who push their gear in wet, muddy, and gritty conditions.
• Riders upgrading a worn or stretched EK 525 chain to restore performance and reliability.
• Bike fleets or shop technicians seeking a dependable, easy-to-service rivet link for frequent chain maintenance.

How it solves real problems

The combination of NX-Ring sealing and a rugged rivet-link design addresses common chain wear culprits: dirt infiltration, lubrication loss, and rivet-head fatigue. By keeping lubrication inside and contaminants out, the Green Rivet Link helps maintain smooth engagement with every pedal stroke, reduces friction-induced wear, and supports longer service intervals between full chain replacements.

What you get and how to use

• A single EK 525 NX-Ring Super H/Duty Green Rivet Link designed for EK 525 chains.
• Simple on-trail or workshop installation with standard chain tools. Steps: align the link with the existing chain, insert the rivet pin, secure and flush the head, then re-lubricate and test for smooth motion.

Pro tips for best results

• Inspect the rivet head after install to ensure a flush seating for optimal power transfer and minimal snag risk.
• Pair this rivet link with a well-lubricated EK 525 chain to maximize NX-Ring effectiveness and longevity.
• Carry a spare rivet link for quick field repairs during long rides or race weekends.
