INTERNAL THREAD TECHNOLOGY (ITT)
Defined: Carbon steer tubes with a layer of high strength epoxy-infused internal threads, eliminate the need for heavy, clumsy internal expander plugs that can slip or damage steer tubes. ITT threads are capable of withstanding 2500 ft/lbs without pulling out.
Advantage: Lighter, stiffer, stronger fork/steer tube system, and easier headset setup and adjustment. Found on: Easton EC90 level forks with carbon steer tubes.
