• so you're measuring or typing wrong somewhere

    Yup, we just checked. Again. She'd entered 71cm instead of 79cm for her inseam. Its correct now!

  • No, probably a slightly different error. I was measuring from where it showed in the diagram, but its appears to be better to just measure just through the seat tube. Mine is still out by around 6cm, but its a lot closer than it was.
