My fatass weighs 250, 270 with all my gear, and I am 6'6". At the very least I need to upgrade my springs. I called FC and they reccommend a .50 for the forks, and a 6.7 for the rear. The increase for the forks seems correct to me, but I questioned the guy about the 6.7 in the rear. He told me because of my height I will tend to ride with more weight over the rear of the bike. Any other tall guys out there run across the same scenario? Does this seem reasonable? I wanted to check before I spend the money. I looked into Race Tech, but it looks like the biggest spring they carry for the front is a .48.
