IRC Tires
IRC BLIZZARD The Inouye Rubber Company, known as IRC by the bicycle industry, like National and Mitsuboshi, is another of the big Japanese tire manufacturers. IRC has made tires of good quality and workmanship for many years. IRC is responsible for the manufacture of the Japanese made Ritchey tires and the to be released in 1993 Yeti For Racing Only tire. The IRC tire under their own name, that has made the biggest impact in the USA is the "Blizzard". The Blizzard is marketed as the tire for snow conditions because it has small steel pins pressed into its tread pattern, in a way, like the steel studs pressed into snow tires used on automobiles. The Blizzard tread pattern is directional and made of two rows of tread blocks which are based on over lapping rectangles with broad spaces between them. The first row is made of three multi-sided over lapping tread blocks. The second row has two of the over lapping style blocks, one on each side, 4mm from the centerline. One of these two blocks will have a steel pin in it. In the next repetition of the tread pattern, the opposite block will have the steel pin in it. The second row also has two small edge tread blocks on each side. We found the Blizzard's tread rubber had a hardness of 72/A. Blizzard 26 x 2.125" $ Price in Catalog
IRC GEO CLAW LITE The IRC Geo Claw Lite is a directional 26 x 1.90" mountain tire. It has a Kevlar bead to reduce weight and comes, at the moment, only in a Skin sidewall model. The Black tread two tread block pattern that repeats every 1.47" around the tire. The first row has a .88" wide center tread block which has the appearance of two "L" shaped blocks, on their backs, joined for a part the base. There is a smaller L-shaped edge tread block which is pitched at an angle. The smaller blocks are placed 2.5mm from the center block. The second tread block row uses two L-shaped blocks, on their backs, in the center, with the bases separated by 6mm. The second row has smaller L-shaped tread blocks pitched at an angle with support that rises from the sidewall. We found the Geo Claw Lite had a tread rubber hardness of 62/A.

In-depth Information About Metals Aluminum Aluminum is extracted electrolytically from bauxite ore. It is made by the electrolysis of aluminum oxide which is found in larger concentrations within bauxite ore. Bauxite is a mixture of the hydroxides of aluminum, together with other impurities such as oxides of iron, titanium, and silicon. Bauxite is produced by the weathering and change of aluminum silicate rocks usually found in tropical and semitropical regions where climate has produced an accelerated weathering process. Bauxite is not a rare ore and is widely available in the US, the Caribbean, and Europe. Approximately 4 pounds of read the full article... Beryllium Beryllium is a specialty metal that is steel-grey metal in color, with an extremely low density, making it very light weight. At 1.85 grams to the cubic centimeter, its density compares to that of magnesium. It is also a high strength metal, making it possible to design light weight, thin membered parts with ahigh stiffness. A column made of beryllium to support a load placed directly downward on top of it, will have a greater load carrying capacity, and be lower in weight than any other metal of equal size. Until the 1950's beryllium was used read the full article... Titanium The element titanium was discovered in 1763 by an English cleric, William Gregor who was an amateur chemist with an inquiring mind. It was in the black sands of Cornwall that he discovered the new element that had up to that time, attracted little scientific interest. A few years later, an Austrian, Klaproth, extracted the same element from an ore widely known as "rutile", which is a mineral consisting of titanium dioxide (one titanium atom, two oxygen atoms), that is a reddish-brown substance with a slight metallic luster. While rutile is the highest grade read the full article... Metallurgic Hardness Testing There are three types of tests used with accuracy by the metals industry,they are the Brinell hardness test, the Rockwell hardness test, and the Vickers hardness test. Hardness is the property of a metal which gives it the ability to resist being permanently deformed (bent, broken, or have its shape changed), when a load is applied. The greater the hardness of the metal, the greater resistance it has to deformation. Since the definitions of metallurgic ultimate strength and hardness are rather similar, it can generally be assumed read the full article... |
