Super tough plain chain from DID.  Features include DID's SDH pin treatment, which forms a super-hard chromium carbide layer on the outside for wear resistance while leaving the core malleable enough to absorb high shock loadings without breaking.  The NZ series also includes solid bushings and quad-riveted pins for great strength.  This has always been our chain of choice for the Farkham Hall YPM race bike.

Tensile strength of the 520 chain is 35.8KN and wear resistance is quoted at 410 (compared to standard chain = 100).  DID NZ chains are supplied with a 'press-together' horseshoe link as standard.  This is far more reliable than a simpler hand assembled split link.  Rivet links are available as an option.

Made for classic bikes, this race-quality chain is our first choice for the Farkham Hall Team racing bikes.
