Tires mounted on the bike were of 26 x 2.125
Size which generally corresponds to modern day Mountain Bike tires. Although
most of the tire companies of the period manufactured that size of tire
(Good-Year, Firestone, BF Goodrich, etc..) it seems US Royal Master Tires were
most commonly used. The US Rubber Company's Chain thread, known as US Royal
Chain, may also have been used. Tubes were off the shelf, as were the Schrader
valve cores and caps.
