Odyssey Headset
ODYSSEY TORO PRO HEADSETThe Odyssey Toro is another entrant into the needle bearing market. Made in Taiwan, the Toro has a locking (cinches around steerer tube) headlock nut as a separate piece not integrated in a single piece. The separate locking nut is made of aluminum in a thin teardrop shape with the narrowness at the riders side. The lock piece has well cut threads for the steerer and a groove that a sturdy Black plastic stem seal snaps into. The narrow side of the lock piece has a hole drilled horizontally through it with threads tapped into the end of it at the right side. This narrow area is then cut through making a cinch mechanism when a steel bolt with a 2mm hex head is tightened. Beneath the lock piece is the upper cup, but because this a needle bearing headset this upper piece becomes the seat for a black steel cone race that is bonded, (and therefore non-replaceable) to the aluminum surface. The top of this cone piece shows good machine work with well cut sides for the headset wrench to grip, and a recess for the Black steel head key washer that is stamped from 2mm thick plate to lie into. The lower race of the upper assembly is made of aluminum, the steel race is again bonded to alloy piece, and there is a groove that holds an O-ring seal around the perimeter. Like other needle bearing headsets the lower assembly has the cup and cone race traditionally positioned. The cup is forged of aluminum alloy and machined to de-burr to make perfect the surfaces so it can be pressed evenly into the bottom of the headtube. The steel bearing race is bonded (glued, cemented) within the alloy cup. The fork cone race, forged of aluminum, has a well polished steel cone race bonded to its upper surface. At the junction of the race and the alloy seat, a recess is formed, that seats a flush mounted O- ring to prevent lower contamination. The Toro uses twenty-two 2.5mm diameter needle bearing that are 4mm long in a Black plastic retainer in each of its bearing assemblies. The tightening wrench isn't included. The Toro comes in 1" or 1 1/8" diameters, in four colors, Blue, Black, Lavender, or Silver. The Toro stack height is 33.5mm, the 1" size weighs 100 grams, while the 1 1/8" size weighs 114.5 grams. 1" (Color- B-BK-L-S) $ 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... |
