The BackBone AFX is a bow-to-stern frame for the Advanced Elements Advanced Frame Expedition inflatable kayak. The backbone enhances both rigidity and performance.
I have found that the backbone does give you a little better ride and a little more speed but with me only weighing in at about 165 its hard to tell the difference
Haven't used them yet - the kayaks seem to track great without them and we are wondering if we will need them at all.
Well built, reasonably light and well protected. After I try it I will let you know what difference makes to my kayak performance. Nice service!!!
Relatively easy to install and seems to enhance stability and tracking some. Not a huge difference it seems though. Not sure if you need it unless you're doing huge amount of paddling.
