Speed Defies Gravity Saddles
SPEED DEFIES GRAVITY S2000This is one of two saddles we are aware of that uses a fabric cover with Kevlar fibers to resist tearing, (the other is the Serfas Tailbones, believed made in Taiwan). The S200 uses a Taiwan made, nylon shell with no molded in anatomical depressions. A molded neoprene foam rubber is used for padding. The foam padding extends the length of the saddle, tail to nose, covers the sides, then feathers into the shell bottom. The fabric cover is glued to the foam padding, and then up under the underside of the shell. The cementing is cleanly performed and the fabric, is well tailored to contour the under side of the saddle nose. There are two rail recievers molded into the shell at the rear, with the rail return curve occurring in a molded bridge two inches from the tip of the saddle. The rail bridge joins the top and sides of the sheel together at the front and has a reinforcing rib that leads to the tip, adding support. The rails are made from 7.1mm in diameter Titanium alloy wire. The exact alloy or it's origin isn't mentioned. If the rails were produced in Taiwan, they would likely be made of Russian Titanium alloy, which we have cautioned against elsewhere (handlebars). We found the S2000 weighed 250 1/2 grams, (not close to the 215 grams that SDG claims). $ 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... |
