Have you ever ridden one??? Graphs mean NOTHING in the grand scheme of things and can be manipulated any way you want based on data manipulation. Who's to say they are even correct? Near as I can tell you got them from that dude from Russia's posts which have proven to be pretty much useless from my personal experience. If what you preach is truth then all of these bikes would ride similarly. THEY DON'T. A TRUE 4 bar design like Specialized uses needs a climb switch - at least every single one I've ever ridden has so... what is the purpose of your post???
