NEW 1/2 X 3/16. THIS IS A HIGH QUALITY HEAVY DUTY DRIVE CHAIN SO THE SIDE PLATES ARE 0.50MM THICKER THAN THE STANDARD RENOLDS CHAIN, I HAVE BEEN USING THIS CHAIN ON TIGER CUBS FOR THE PAST 20 + YEARS AND IT PERFORMS AS GOOD AS THE MORE THAN DOUBLE THE PRICE RENOLDS CHAIN AND FITS THE SPROCKETS PERFECTLY.
