Ritchey Hub Skewers
RITCHEY STEEL LIGHTNING RODSRitchey Lightening are made in two models in Taiwan. The lever is made of machined aluminum that is 80mm long and 1/2" tall. The handle of the lever is curved with the center area cut away to reduce weight. The lever uses a rotating external cam to tighten. The cam rotates against a concave Teflon surface which is imbedded into the back of the contact washer. The Teflon surface allows the contact washer to smoothly adjust and seat while closing the skewer. The contact washer is 18.9mm in diameter and has a serrated face. The nut is machined from aluminum rod, and has 19.1mm contact diameter. A plastic insert into the threaded portion of the nut making it act as a lock nut. The inner side of the nut is serrated to grip the fork blade. A single 3.2mm wide knurled ridge provides the grip surface to hold the nut in position. The volute springs are made of flat spring steel. The pivot pin holding the skewer is made of stainless steel, as is the skewer rod. The front Lightning Rod weighs 49.5 grams, while the rear weighs 55 grams. The aluminum parts of the Stainless steel Lightning Rods is anodized in Black. $ Price in Catalog RITCHEY WCS TITANIUM LIGHTNING RODSRitchey also has a second version of the Lightning Rods that has a Titanium rod in place of the stainless steel one. We are told the Ti rods for these are actually made here in the United States, in the northwest, either Idaho or Montana. Using US made Ti rods assures the quality of the Titanium metal used so inexpensive and questionable alloys from Mainland China or Russia wouldn't find their way into the Ritchey skewers. All other parts however, and the manufacture of the skewers in performed in Taiwan. The weight of the front Ti Lightning Rod skewer is 39.5 grams, and the rear weighs 42 grams. The aluminum parts of the WCS skewers are anodized a light Gold (WCS) or Silver color. Color-G-S / T $ Price in Catalog |

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... |
