>>1841439Seems like it by my own measurement, but here's the chart. Mind you the 820 was/is a casual everyday bike, so it's probably way less aggressive than the Kona, the 900 series bikes from the same catalog do say 580 for an 18".
Which kind of answers my initial question, huh, guess the 820 was a bit short for the size and time, I think the geo seems more similar to the early 90s models now that I'm looking into it.
