650C Bicycle Tires from Harris Cyclery
(ISO/E.T.R.T.O. 571 mm)

571 mm / 26 x (fraction) / 650C tires

Very narrow tires in this size are used on some time-trial bicycles and high performance road bikes for smaller riders.

(Heavy, wide tires in this ISO size are used on older Schwinn cruisers and some Canadian bikes (26 x 1 1/2 F.12.)

There are no medium-width tires available in this diameter, just very narrow road tires and wide cruiser tires.

Frequently confused with the 559 mm size, since both are commonly referred to as "26 inch ."
