Magura Grips


GOMMITALIA / MAGURA CORK GRIPS

There are two grips from Europe that are unmistakably similar enough to have come from the same factory. We believe that Gommitalia of Italy is the maker but they are also sold as Magura grips. Magura, like Answer has primarily made their name by making motorcycle parts. This pair of grips are made of very light, Black colored, foam rubber mixed with a small amount of light Brown cork wood. The grip has a smooth outer surface that is 1.3 inches in diameter at the inner end, flaring to a 1.6 inch diameter at the outer end. The outer 8/10" (20mm) of the grip is solid, leaving a thick end to help prevent tearing in a spill. The "cork" grips are made in Black only, 5.3 inches long and weigh an unbelievably light 34 1/2 grams per pair. We found that they had a durometric hardness of A/36. These appear to be a good, very simple, lacking ego on the makers part pair of grips and though pricey, are unquestionably the lightest. These are the grips we vote "most likely to be copied by others". $ 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...
