Just about every human has either longer or shorter arms, legs, torso, wide azzz or skinny azzz long or short neck, etc. No bike, by any manufacterer will fit everyone perfect, right out of the showroom. They just make them to fit an average frame- what ever that is. Personally, at my age, I figure my F6 may well be my last "big" cycle, so I have no problem adjusting some parts to make it more comfortable. I can say that I think the 6 comes with a Great platform to start! Now, if only I could control the weather. Winter sucks.
