Onza Grips

There are limited quantities of Onza grips. Onza filed bankruptcy in 1996 and the brand name has been bought by the company that distributes GT bicycles... known as Riteway. Whjat will become of the OnZa brand name now is un-certain.


ONZA PORCIPAWS MOUNTAIN GRIPS

Onza Porcipaws are an extremely thin walled grip with the Onza logo and a porcupine caricature raised from a 3mm thick grip sleeve. The raised area brings the grip thickness to 4.3mm. At the inner end is a groove for wire of zip tie application. There is also a wire groove at the outer end of the grip. The outer end is closed off with extra thickness to help prevent ripping in a fall. Onza also includes a pair of light weight polycarbonate plastic end plugs, knowing some of their users will ultimately "trash" the end of the grip. The grip has on the inside a raised ring at both ends, which acts as an O-ring seal to keep water and dirt from migrating under the grip and loosening it. A pair of zip ties come to fit the wire groove with each pair so the grips really come complete. Onza Porcipaws weigh 66 grams per pair, the end plugs weigh 3 grams, they are 4.6 inches long and come in either Black, Clear, or Lavender. Made in Taiwan, they have a durometer hardness of A/39. $ Price in Catalog

ONZA ULEƒS MOUNTAIN GRIPS

Onza UlŽes (oo-lays) are also a thin walled grip. They have a relatively smooth outer surface with three depressions around the circumference for the hands middle three fingers to lay into. There is a trough 3/8" form the outer end, and another 7/8" from the inner end, each to allow the grips to be wired onto the handlebar. The Onza Porcupine logo appears as a recess four times at the outer end and twice near the inner end of the grip, while the OnZa logo appears four times as the grip wall thins at the inner end. The grip wall is 19/100" thick at the outer end and 10/100th of inch at the inner end. The UleŽs grips are open at both ends and the grips come with a pair of molded Black plastic press- in end plugs. These plugs are the same ones that come with the Ritchey grips, and the Specialized bar ends, just the logo is different, leading us to believe the grips may be made by Co- Union. (One of the OnZa founding partners worked for "Tioga" / Oriental Boeki Corp. / Marui Ltd before founding OnZa. The Tioga/OBC/Marui link to Specialized is well known) Inside the grip, just near each end is a slight raise. This inner ridge assists in holding the grip in place and preventing drip from wedging between the grip and bar. The grips are 5" (125mm) long, have a pair weight of 75 grams and a durometer hardness of A/39. The Black end plugs weigh 4.5 grams per pair. Made in Taiwan they are available in Black or Lavender. $ 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...
