Grisley Bar Ends
GRISLEY CLAWS BAR ENDWe have stopped selling these because they never really took off, this review is for historical purposes. They may still be available in some stores. P.R. Grisley of Salt Lake City, Utah make a bar end set that can't be simply described as either a ski or L-bend. They have a compound bend tucking the thumb and fore-finger inward slightly. The cinch assembly is cast and machined stainless steel, that has the a 15 degree inward angle for the grip section built into it. The cinch assembly uses a 6mm by 1mm thread pitch steel bolt that is 10mm long. It has a 5mm hex head fitting and weighs 4.5 grams. The grip tubing is made of 6063 aluminum alloy, with an overall length of 5 inches. It is epoxy bonded and tightly press fit to the cinch assembly. The aluminum end cap at the end of grip tubing is brass plated with the relief of a grizzley bear on it. For the handlebar ends two chrome plated press-in steel caps are provided. The cinch assembly is Silver, the grip tubing end cap is Gold colored, and the grip tubing is anodized in Black, Lavender, or Silver. The weight of a set of Grisly Claws with the Chrome end caps weighs 190.5 grams. We're not sure when these became unavailable. Because their was no real interest in them we never really had many on hand. We have heard, but have not been able to confirm, that Grisley is involved in designing bikes made in Asia for import to the United States. At the end we sold these bar ends for $44.99 |

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... |
