THIS IS A NOS NEVER USED MURRAY KING KAT BICYCLE RIM. STAMPED M.O. MGF. CO. THIS RIM HAD HEAVY DUTY SPOKE HOLES ON IT, IT TAKE 12 GAUGE SPOKES. IT HAD 28 SPOKE HOLES. IT WILL FIT MANY MUSCLE BIKES AND OTHERS. IT WILL TAKE 20 X 2.125 TIRES OR 20 X 1.75 TIRES. THIS WAS FOUND IN A OLDER WAREHOUSE OF MURRAY BICYCLE / PARTS. THIS IS FROM 70S / 80S. FOR HOW OLD IT IS, THE RIM STILL IN AMAZING CONDITION, THE CHROME IS STILL LOOK BEAUTIFUL. THERE MIGHT BE SOME SHELF-WARE FROM STORAGE AND MOVING AROUNF OVER THE YEARS BUT LOOK PERFECTLY FINE. I FOUND A FEW BUT DO NOT HAVE TO MANY LEFT SO GET IT WHILE YOU CAN AS NEW OLD STOCK ITEMS IS VERY HARD TO GET NOW.
