An internally supported cable system control for a bicycle that does not interfere with the steering mechanism and does not require the structural integrity of the bicycle frame to be compromised. In the disclosed internal cable system, the control cables are routed through a passageway in the gooseneck and the bicycle frame to the mechanism or device that they are designed to control. The gooseneck design is unique in that it allows for an unobstructed passageway for the cables to travel into the steering tube and frame, while allowing for both sliding forward and rearward as well as raising and lowering, as desired by the bicycle rider. For aesthetic reasons, a casing may be added to cover the cabling between the control levers and the gooseneck.
This patent claims the benefit under 35 USC 119(e) of provisional application No. 60/457,555 filed on Mar. 26, 2003 which is incorporated herein in full by this reference to it.
An embedding typed handbrake operating device is disclosed herein, which mainly contains a positioning seat to which an operating lever is pin-joined. A stopping ring, a spring, and a locking seat are sequentially joined to the positioning seat through a locking bolt. The brake sleeve of a brake cable is threaded into the tubular body of the end section of the handlebar via a cable entrance hole and then into the locking seat. A brake wire is threaded through the operating lever, an axial through hole of the locking bolt, and into the brake sleeve connected to the locking seat, and finally to the handbrake assembly.
A telescopic steering system for a cycle includes a frame, a handlebar, a guiding piece, a steering column fixed to the frame, a plunger sliding and rotating axially in the steering column, a fork fixed to an end of the plunger, and a front wheel of the cycle positioned on the fork. Additionally, the guiding piece transmits rotational movement from the handlebar to the plunger.
A bicycle front end assembly is provided which is configured to reduce aerodynamic drag. In particular, an axis shaft of a fork may be mounted to a head tube of a bicycle frame. A fork head may be disposed in front of the head tube for providing a front end assembly which is aerodynamically configured while providing an increased moment of inertia compared with traditional designs to reduce drag of the bicycle and increase steering stiffness. Also, the handlebar may be attached to the fork head such that when the bicycle is steered to the left, the fork head is rotated toward the left and when the bicycle is steered to the right, the fork head is rotated toward the right. In this manner, the fork head is alignable to the travel direction of the bicycle.
