When did this new incorrect designation for 584 tires start? 650B no longer cool enough for the gravel crowd?
Why incorrect? is it not the ERTRO system designation?
Is this directed at me? I went with 27.5 as they're mtb tyres
27.5" is roughly accurate for the outer diameter of the tyre. It's 26" that's wrong (more like 26.5")
