Well I ran across the Alpha Q website. That's the company associated with Tru Temper and they make the carbon forks. The system they use is an aluminum insert tube epoxied into the carbon steerer tube. The insert tube has a fastener integrated into the center of it somehow. They claim it provides a good clamping surface internally, gives support to the steerer tube where it is clamped by the stem and lastly adds rigidity to the fork assembly.

I ordered one as they are sold separately for installation into your fork. This is what they have to say on their web site:

"Q: Do I need to use the Insert Kit supplied with the all-carbon forks? Will a compression plug work?
A: You must use the insert to comply with the warranty. A compression plug provides an anchor for the head set tension bolt. The insert does this and more. It also reinforces the steerer at the clamp area to support the clamping force of the stem better than any carbon tube with only a compression plug. Thirdly, the insert stiffens the top portion of the steerer for a more solid feel in the stem and handlebars where torque is generated. The insert provides the most solid connection possible and is well worth the time to install it."

Thanks for the help. I'll let you know how the install goes.
