Abstract
An apparatus for removably securing an electrical element within a tubular steerer tube within a frame element consists of a canister for housing the electrical element, an expandable sleeve, and an expansion bolt coupling the canister and expandable sleeve to actuate compression of the expandable sleeve thereby securing the assembly within the tubular steerer tube. A preload cap is secured to the assembly to retain a bearing system to permit the steerer tube to rotate relative to the frame. One or more of a light, switch, and connector may be disposed in the preload cap to provide system conditions, controls, charging, communication, and so on. In certain embodiments, requirements for a central extension bolt extending from preload cap to expansion bolt are obviated, providing a relatively uninterrupted volume within the steerer tube in which to house electronics, route wiring, and so on.
