A bicycle wheel basically has a hub, a plurality of spokes extending outwardly from the hub and an annular rim coupled to the outer ends of the spokes for supporting a tire. The annular rim has a spoke attachment portion with a plurality of openings for receiving the outer ends of the spokes therein. In the most preferred embodiment, the bicycle wheel is a one-piece, unitary wheel. Preferably, the one-piece, unitary bicycle wheel of the present invention is produced by die-casting. The preferred material for bicycle wheel of the present invention is magnesium (Mg). A centrally located rib portion is located between adjacent spoke portions and to reinforce the rim portion between spokes. Rib portions extend radially inwardly from the inner peripheral surface of rim portion. Preferably, the middle segment of each of the rib portions has a radial height that is approximately equal to the base rim height plus more than half of the base rim height. The shapes of spoke portions are designed to absorb the vibrations from the ground as it is being used in the bicycle. This shock absorbing function is enhanced by the use of magnesium for the wheel.

An aqueous dispersion composition comprising a fluorine-containing melt-processable resin powder having an average particle size of 10 to 1000 .mu.m, a water-soluble solvent, a surfactant and water, and said fluorine-containing melt-processable resin powder being contained in an amount of 15 to 80 % by weight. Without generating cracks and pin holes, a thickness of coating film per one application can be increased more than 1 mm, and a total thickness can further be made thicker.

Electrodeposition coating method and electrodeposition coating agent

A bicycle derailer of the type wherein a movable derailer member moves relative to another member for positioning the chain guide relative to a first sprocket and a second sprocket. An indicating member is disposed on one of the movable derailer member or the other member, and indicium is disposed on the other one of the movable member or the other member. A relative position between the indicating member and the indicium indicates a position of the chain guide relative to the first sprocket and the second sprocket. Thus, the derailer may be adjusted to a desired position by moving the chain guide so that the indicating member is set to a desired position relative to the indicium.

Fluororubber coating composition

Colloidal polytetrafluoroethylene fine particles having an average particle size of 0.05 to 1.0 .mu.m and each comprising a core made of polytetrafluoroethylene which has a high molecular weight and can be fibrilled and a shell surrounding the core and made of a low molecular weight polytetrafluoroethylene which is not fibrilled, which has good dispersibility in water or an organic solvent and easily provides an organosol by a phase transfer method.

Polytetrafluoroethylene fine particles and powder

An aqueous dispersion comprising an aqueous medium and colloidal particles of a fluorine-containing copolymer having an average particle size of about 0.05 to 1.0 um dispersed therein, each colloidal particle being constructed with a core portion made of a polymer comprising about 99 to 100% by weight of units of tetrafluoroethylene and about 0 to 1% by weight of units of at least one other fluoroolefin and a shell portion made of a polymer comprising about 50 to 97% by weight of units of tetrafluoroethylene and about 3 to 50% by weight of units of chlorotrifluoroethylene, the amount of chlorotrifluoroethylene in the core and shell portions being from about 2.5 to 25% by weight based on the entire amount of the core and shell portions.
