Specialized HandlebarsSPECIALIZED HANDLEBARSThe Specialized color trade catalog for 1993 accessories showed 6 different handlebars and described 7, one the HardRock went un-photographed probably because it was a less desirable all steel handlebar with a 2" center rise. The 1994 color trade catalog for accessories showed that they had already discontinued all but 3 of them. Not a very strong belief in their line of handlebars. But lets take a little of the mystique out of this, there is no Specialized handlebar factory, they sell handlebars that are actually manufactured in the orient by other companies within the bike industry. A well placed source has revealed that the company "Strong", located in Japan and a known maker of stems, seatposts, and handlebars is the real manufacturer of the Specialized brand mountain handlebars that are "drawn" of aluminum and sold as the Rock Barª and the Team Edition bar. Those Specialized branded handlebars that have a "sleeved" center, which for 1994 means only the Mod V are made by the Japanese company "Nitto". Nitto is also a known maker of stems (included Ritchey branded stems), seatposts (including Ritchey branded seatposts) and handlebars. We will review their Rock Barª only, because it's the only one of their handlebars still made since last year that we have actually found Specialized to inventory.
SPECIALIZED ROCK BARªThe Rock Barª is made of 6061 aluminum alloy with a T6 temper by, as we are told, the Japanese company Strong. The Rock Barª is an ATB flat bar with a 4 inch long bulged center section that has 1 1/2" long knurls laid horizontally around the circumference. The center section has a 25.4mm outer diameter, while the ends have a 22.2mm diameter and wall thickness of 2.6mm. The inner diameter of the Rock Barª at the ends is 17.9mm. The Rock Bar is 589mm (23 3/16") long and has a 6 degree bend with a smooth outer surface. Though Specialized states in its accessory brochure that's available in Black, Red, or Silver, their price list un-characteristically shows a listing for Black only, from which we have concluded that Black is the only production color. Its weight is also a point of contention. In the 1993 and 1994 product brochure Specialized describes the weight of the Rock Barª as "less than 200 g". However the 1992 product brochure is much closer to the truth when it states the weight the Rock Barª as "275 g.". The Rock Barª actually weighs 270 grams. We find this deliberate deception of the past two seasons rather distasteful. If there are no overt benefits to a product, not marketing it would be preferable to misleading customers. This is also an item where Specialized hasn't set a "perceived minimum retail" so we are actually free to sell it for considerably less, as a percentage of our cost, than we are permitted to on most Specialized goods. $ 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... |
