I get you Jim............it occurs to me that these tall head tubes and up sloping head tubes minimize the whole triangle thing and the second top tube restores that. This of course keeps the bar position high at same time keeping the frame stronger plus the frame also fits more variable sized riders ( the real reason) and allows a bit more clearance over the top tube. On the other hand.....The level top tube and low head tube is the traditional look but those dang bars end up too low for most of us aging bicyclers for rides longer than five miles. I figure there's more than one way to skin a cat and they are just bicycles so......go Grant, you make some fine machines !
