I'm considering a small Honzo, but Kona's geo chart states 31.5 inches which seems higher than most other 29er frames in a small/16" size. I noticed from Kona's geo diagram they measure a few inches in front of the BB rather than directly over the BB. Does this explain why it's about 1-2" more than "normal"? Can someone verify on their Honzo build, if the SO is accurate and how much less the measurement is if taken directly over the BB? I probably shouldn't worry too much about SO, if all other measurements look good, but it still has me slightly nervous nonetheless.
