Abstract:
The present disclosure includes a bicycle wheel having a hub, a plurality of spokes, and a rim. The spokes are connected to the hub, each spoke having two ends and a major axis. The ends of each spoke are substantially aligned with the major axis of such spoke. The rim provides a plurality of fixed spoke mounts secured to the spokes. The spoke mounts provide stress grading, in one preferred embodiment by decreasing in section as they extend away from the main body of the rim toward the hub. The spoke mounts are formed integrally with the rim and avoid the use of holes through the wall of the rim that seats the tube. Spoke adjustment mechanisms for straight spokes attached to such spoke mounts are also provided. The disclosure also includes a method of constructing a wheel.
Abstract:
Pneumatic tires adapted to use on bicycles have a number of criteria that need to be evaluated. For high performance bicycle riding, such as in mountain bike races, it is advantageous to optimize performance. Standard tires with tubes have ease of repair in the replacement of a punctured tube, have the ability to maintain pressure for long periods, and do not require special adaptation of the rim for sealing.
Abstract:
Wheel rim whose radially exterior geometry comprises an outer and an inner rim seat, a bearing surface formed essentially as a cylinder of revolution to receive a tire tread support ring, and whose radially interior geometry does not increase between the said mounting groove and the zone of connection to a wheel disc, which is made up by assembling a first, metallic structure constituting the radially interior geometry of the said rim and at least part of the radially exterior geometry of the said rim; and a second structure designed to constitute the said bearing surface radially on the outside, wherein the said second structure consists of an annular support element comprising at least one essentially axial opening and which comes in contact with the radially outer wall of the said first, metallic structure.
Abstract:
The invention relates to a tubeless mounted assembly for a cycle, more particularly for a bicycle, consisting of a rim and a tyre. A mounted assembly of the tubeless type for a cycle consists of a rim and of a tyre comprising in particular beads, said rim consisting of two wings, attached to two seats, intended to receive the beads of a tyre. According to the invention, the rim and/or the tyre comprises means for stabilising the pressure of the air at the level of the outer surface of the tyre, in the zones which are neither in contact with the ground nor in contact with the rim, to a value lower than 2 bar. The invention is directed also at a rim for a cycle wheel and a tubeless tyre for a cycle.
Abstract:
The present invention provides a compound, system, and method for retrofitting and converting standard bicycle rims and tires having tube to be tubeless. Standard tube tires are retrofitted by installing either rim tape or a rim strip with integral valve stem around the inner channel of the rim, mounting the first bead of the tire, injecting a liquid sealing compound into the tire cavity, finishing mounting the tire, inflating and installing the tire on a bicycle. The sealing compound may additionally contain propylene glycol or an aggregate material to encourage the sealing of the tires as punctures occur when the tire system is placed into use.
Abstract:
A bicycle rim includes a plurality of holes defined therethrough and each hole has a recess defined in an inner periphery of the rim. A diameter of the recess is larger than a diameter of the hole so that an end of a spoke is engaged with the recess. A screw extends through the hole in the rim and threadedly engaged with a threaded hole defined longitudinally in the end of the spoke.
Abstract:
Disclosed are improved wheels and tires for simulating the appearance of larger-diameter wheels mounted within low-profile tires. The improved tires are intended to be mounted on wheels with an extended outer flange. An embodiment of the tire comprises an outboard tire wall, an inboard tire wall, a tread therebetween, a laterally extending wheel protector, a ledge, and a flange seat. The flange seat is optionally contoured to match the inner face of an outer flange of the improved wheel.
Abstract:
A connecting method of a wheel rim of a bicycle includes the following steps: forming a wheel rim, inserting an inner connecting member between two abutment ends of the wheel rim, connecting the two abutment ends, heating, packing, permeating, and returning. Thus, the structural strength of the wheel rim is enhanced, thereby increasing the lifetime of the wheel rim. In addition, the connecting seam of the two abutment ends will not form a protruding rough bur, so that it is unnecessary to perform a secondary working process to grind the surface of the connecting seam of the two abutment ends, thereby simplifying the working process of the wheel rim, and thereby decreasing costs of fabrication.

Abstract:
A bicycle wheel rim includes two retaining portions and a locating portion. The two retaining portions are formed of a groove for retaining permanently one of two retaining edges of a tubeless tire. The locating portion is formed of two furrows, and a ridge situated between the two furrows which are located in proximity of the grooves of the retaining portions. The furrows are used as temporary dwelling places for locating the two retaining edges of the tubeless tire in the course of the mounting of the tubeless tire on the bicycle wheel rim.
