In March 2019 I had the privilege to service the original Suntour New Winner 6 speed freewheel on an exceedingly early 1981 Tom Ritchey Mountain Bike, serial number 91. Steve in CA had acquired it from a museum in NC. It had not been ridden in decades and the freewheel was locked into a fixed gear. I discovered the adjustable bearing race had been cracked and the inner body not in "round." This probably occurred due to freewheel threads seizing with the hub threads. The force of removal by the two-notch tool deformed the circular shape of the body and caused the crack. Internal cleaning, new parts, and fresh synthetic grease brought this historic Ritchey back to tip top, original riding condition!
