I hope Guy won't mind my stepping just a fraction outside his vision for his thread, as the attached photo doesn't belong to anyone on here. But just to illustrate EdEdwards' perceptive point, here is a Kona with almost no slope in its top tube, because it's in the rather rare size 23.
Although ironically, the owner has his seat quite low and has flipped his stem, so he could have achieved that riding position with a size 19 if he wanted to. He obviously likes a long top tube.
Anthony, that's fine, not a problem, any info about Kona's you given out is always interesting and I learn some new things at your posts this year. That Kula Supreme is the biggest Kona's I have seen
the rider would benefit having a smaller frame and still have the same seating/handling postion as this one and make it lighter aswell better looking bike, that is a real 'gate' bike!
