The 650C (571mm ISO) is different than the 26 x 1 1/2" / 650B (584mm ISO).

The 26x1 3/4" (Schwinn S7) has the same ISO as 650C, but is not interchangable due to the bead type.

So much for Standards; I thought the standards were to eliminate all these other standards and conventions. But then we have the headset standard for bikes. And then there's bottom bracket interfaces. And spoke thread and pitch.

Would abike shop in europe have a more dificult time than the ones in the US stocking tires because of the proximity of other countries and their own national standards on tires?

Gotta go back to work and avoid geeking out about obselete tire bead diameters.

Tom Martin Oakland CA So there, tolja. Not easy in the trenches. I can tell ya, no bike shop ever earned a dime on a spoke, maybe not even a penny. We have aroom with barrels of usorted spokes. People buy 'em, get the wrong size, swap 'em (sometimes they come from mailordersources and we swp 'em anyway. we also sell onesy twosy and many just sell half-wheel packs and no advice. Then there's rium, drilling, sizes.. it goes on Here cxomes a truck with 40 boxes to unload.
