    Whats up with this IRO geometry

    So I've decided to either get an IRO or Bare Knuckle frame. I'm leaning towards IRO, but the geometry just seems kinda wack. I normally ride a 50-52 frame. IRO has a 50cm with s/t 46 cm and t/t 52. The t/t seems to be the correct number, but that s/t number seems awfully small. If I move up to a 53cm, it has a 49cm s/t and a 54cm t/t.

    It just seems weird that theres such a huge difference in length of s/t and t/t. My old basso frame has a 51cm s/t and a 52cm t/t which seems just about right. The Bare Knuckle on the other hand seems more reasonable with a 50cm s/t and 53cm t/t.

    Anyone see any reason why the IRO seems to have such a long t/t in relation to the s/t?

    Well, you've got a good 4 cm of ST showing above the center of the TT.

    Haha well then, does anyone have a size 50cm IRO frame they got in the group buy, but no longer want? I was a bone head and couldn't decide if I wanted one or not, and now I'm kicking myself in the ass. I'm considering a used bare knuckle for 400 or a new IRO for 329. Hell, maybe the bare knuckle is more worth the money considering they go for 600+ new.

    Where are you getting this new $329 IRO, exactly? If it's somewhere online or something, I'm going to kick myself for just buying a used Fuji Track for almost that much.

    $329 for the Angus
    $249 for the Mark V

    These are frame/fork only by the way. Add $300 for complete bikes.

    i'm pretty sure that bareknuckle uses track geometry and iro uses road geometry which makes tt longer. my friend rides a 50cm bareknuckle. it is basically the same size as my 53cm IRO Mark V but he has toe overlap and i do not.

    st length on the iro is that short because of the higher bb.
    most track frame st's are normally shorter than the numeric frame size. it's nothign to worry about.
    sizing is always done by top tube length.

    stand over is a mild issue on a track bike bc you arent supposed to get on and off, and you arent supposed to sway the bike beneath you that much either.

    a 50 cm IRO rides like a 50 cm. first, those are center to center measurements. the top tube of a mark v is teardrop shaped - bigger than standard round tubing. secondly, IROs have a high bottom bracket. third, seat tube measurement is irrelevant. look at standover height and top tube length to guess at fit.

    people need to get over being weirded out by the numbers on IROs geometry charts. they're not that crazy.
    the hipster myth.

    i practice vagabondery.

    Is the IRO that harsh? Or is the BK just that much smoother.

    Or did you use stiff wheels, or did you have a bad saddle?

    i find the best way to have a smooth ride is to ride smooth roads

    an iro should be fine for that

    whoa, you're right. turns out i'm into BDSM and I can't get enough of these potholes

    I just think the higher quality tubes on the bareknuckle would be worth the extra $80, plus everyone and their momma has an IRO

    In about two months, their dogs and their complete extended family will have them too.
