EK CHAIN 520SRX2 QX-Ring 520 Universal ChainRef : EKC00602A / 1129892041

EK 520SRX2 QX-Ring Chain 520 — manufacturer reference 520SRX2-STL 120 SLJ. Designed by EK CHAIN, this 520 SRX features a robust construction tailored for the transmission of road, trail, cross, and quad engines. Its steel/steel finish gives it a sleek look and mechanical resistance suitable for the daily riding demands.

The QX-Ring technology equips the links to maintain internal lubrication and limit the infiltration of dust and grit: a benefit for reducing wear on pins and bushings on rough roads and terrains, without additional quantified promises. The entire assembly is optimized for mounting on standard 520 sprockets and crowns, with a useful link count for longer configurations.

• Pitch: 520

Ideal for maintenance interventions and standard replacements, it can be mounted and adjusted with standard tools (tensioner, clip remover, or riveter depending on riveted installation). A pragmatic choice to get the transmission back in working order.
