Specialized Saddles
SPECIALIZED PROLONG RACE SADDLEThe Specialized Prolong saddle is made nearly an inch longer in the nose than most of the other saddles. It is 11 3/8" long, tip to tail, without the added weight of a full length rail. It is manufactured in Italy, by Selle San Marco to Specialized specifications. The shell is made of molded nylon, with anatomical depressions to fit added padding in needed areas. The shell is covered with molded, high density foam padding, that is luxuriously thick on top, thinning on the sides and feathering into the saddle shell at the bottom edge. The foam support is covered by a very smooth Black leather that is cut with care, and glued cleanly to the bottom of the inner shell. The height of the front half of the saddle is cut shorter so the Prolong isn't as wide, producing less leg chafing. The Prolong has two rail receivers molded into the shell at the rear and a front rail bridge that is a solid block, re-enforcing both sides of the shell at the nose. The rails are made of spring steel, that is painted Black with the return curve at the front. The return curve is 1 3/4" from the tip. Made in Black only, the Prolong weighs 303 grams. $ Price in Catalog
SPECIALIZED PROLONG TITANIUM RACE SADDLEThis is the same saddle as the one above, with one functional and one cosmetic difference. The steel rails in the Prolong have been replaced with rails made of Titanium 6Al-4V rod to reduce weight. The cosmetic change is the inclusion of two added decals on the rear of the saddle. On the left rear is the Wilderness Trail Bikes logo in Red and White, which reveals the consultancy relationship WTB has with Specialized. On the right side is the Specialized Team Edition logo in Red and White. The return curve is 1 3/4" from the tip. Made in Black or Grey, the Prolong Titanium weighs 234 grams.

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... |
