A bicycle crossbar for attachment between a head tube and seat tube of a bicycle and for providing cable concealment and increased structural integrity to the resultant bicycle frame. The crossbar comprises an elongate, rigid tubular member having a groove formed within and extending longitudinally along the side wall thereof which is sized and configured to accommodate three cables of the bicycle. The crossbar is formed in a manner wherein the side wall, including the groove formed therein, is of greater thickness at its end portions. The crossbar further includes first and second cable receiving members which are rigidly secured within the groove and adapted to facilitate the entrance and exit of the three cables into and out of the groove.
A master cylinder is disposed forwardly of a rear fork. A brake hose extends from the master cylinder to a brake caliper. The brake hose has a first U-shaped portion formed between the master cylinder and a portion of the brake hose fixed to the rear fork. A second U-shaped portion is formed in the brake hose between the portion fixed to the rear fork and the brake caliper. The second U-shaped portion is held by a first hose guide. Adjustment in the position of a rear axle relative to the frame, to accommodate elongation of a drive chain, is absorbed by the second U-shaped portion. Suspension movement of the rear axle relative to the frame during travel is absorbed by the first U-shaped portion.
The deflection of a flexible linear body disposed between first and second members is relatively changed in position for easy restriction. A guide is integrally formed of soft synthetic resin and is mounted between an inner tube and an outer tube of a front forked portion for holding an intermediate portion of a brake hose connected to a brake caliper for braking a front wheel of a motorcycle. The guide includes a pair of ring-like mounting portions fixed to the inner tube and the outer tube, a band-like bridging portion for connecting both the mounting portions to each other, a plurality of holding portions provided on the bridging portion for holding the brake hose. The bridging portion has a flat rectangular sectional shape and is mounted to be curved in the X-direction. The bridging portion is easy to be deflected in the X'-direction and is difficult to be deflected in the Y-Y directions so that the brake hose does not interfere with a boot and the front fender.
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.
A high production net shape filament winding manufacturing process and resulting products are disclosed. The manufacture of bicycle frame and their components from filament wound components which have been cut from a section of filament wound stock is disclosed. Also disclosed is a bicycle frame and its manufacturing process and a composite bicycle fork and components thereof.
