    Why?

    Why do my newish continental tires say 28 x 2.1 and fit on my 29'r wheels, but look more like 1.9's?

    28" and 29" share the same rim specs, 622/700c or whatever people chose to call it.
    The 28" denomination, that's a German thing. They chose to follow their beliefs and traditions over acknowledging (sp?) the new standard.
    Same goes for the width they put on the tire. Germans and French often like to measure their tires laid flat out, between two randomly chosen point on the carcass. Takes away all the relation between size printed on the sidewall and it's size when actually inflated on the rim. It's an indistrial thing they like to hold on to, continiously disappointing riders that order a 2.1" because they want something that feels big. 2,1" as in, over 2", thus wider than average.

    What Cloxxki said. The "28" designation is because they refuse to recognize the "29" designation that is now in widespread use. 700c, 28", and 29" all use the same bead seat diameter, so don't worry about that part.

    As far as being labeled 2.1 and turning out to be more 1.9, well that's just Continental being Continental. Every Conti tire I have owned - 700c, 26" and 28/29" - was substantially narrower than the stated width.

    (imagine 'allo 'allo German accent here, for those that get Brittish humor on the tele)
    "You were just measuring the wrong points of the tire, while inflated. What were you thinking?"
