Tioga Mongrel & Bloodhound Tires
TIOGA MONGREL TIRESThere are three models of Mongrel tire, all are made in Japan, all have a Skin sidewall, and they all use a steel wire bead. The three sizes are 26 x 1.5", 700c x 38c, and 27 x 1 3/8". The Mongrel is largely for pavement use, having a shallow tread design. The tread is made of six vertical rows of oval shaped tread blocks, with three rows on each side of the centerline. The inner two rows have narrower ovals than the next two outer row, which has smaller ovals in width than the two outermost rows. The 700c and 27" diameter models have an added edge tread block in the form of a rectangle with a convex roundness on the inner, long side of the rectangle. The Mongrel's tread isn't thick enough to accurately measure its hardness on any of the three models. The 26" diameter Mongrel had a total thickness at the center, including three layers of casing fabric, of 4.5mm, while the 700c model is 4.7mm, and the 27" is 4mm.

TIOGA BLOODHOUND TIRESThe Bloodhound is an all-purpose tire for Cyclo-cross and Hybrid riding or possibly off-road touring. It's available through us in two sizes, 27 x 1 3/8" or 700 x 38c. The 26 x 1.25" size though "made" we haven't found through normal distribution. Both models of the Bloodhound are made in Taiwan probably by the Cheng Shin factory, because of mold markings near the chafing strip. Both models have a steel wire bead and a light "gum" colored Skin sidewall. The Bloodhound is a directional tire with forward pointing arrows molded into the casing. Its tread design relies on two rows of tread blocks to make one tread pattern, which is repeated at 1.07" intervals around the tire. There is a square shaped block at the center with a sloping top and bottom. A multi- sided, but square based edge tread block with support rising from the casing appears at both sides. Above or below is a row that has two center tread blocks made of small vertical rectangles each beginning 1.5mm from the centerline. The second row also has the same edge tread blocks. Between each row of tread blocks, in a sense linking them together, is a coffin-shaped ellipse with the wide area in the forward rolling direction. The coffin shaped blocks appear between the center block and the edge blocks. The Bloodhound tread isn't thick enough to accurately measure the tread stock rubber hardness. We found the center thickness of the 27" tire to be 4.9mm, which includes three layers of casing fabric, while the center thickness of the 700c model was 5.3mm.

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... |
