Third Eye Bicycle Mirrors


THIRD EYE MIRRORS

Third Eye makes four models of rear view mirror using a 1 1/2" or 37mm diameter shatter proof plastic mirror element which is flat, not convex. The mirror elements swivel on a ball and socket joint at the end of a holder arm which extends from the helmet or eyeglass mount. The mounting style is the difference in the four models. The mounts are for hard shell, soft shell, eyeglasses, or a "Pro" model that mounts on the exterior of either a soft or hardshell helmet. The hardshell helmet mounting fits around the bottom of the helmet's shell with the extension arm screwing into the mount, compressing the shell against the inner back side of the mount, holding it in place. The eyeglass mount fits all eyeglasses, using a three contact clip which is pressed down and over the earpiece, with a ball and socket joint independent of the extension arm's ball and socket, to permit infinitely adjustable positioning. The mirror extends ahead and at the side of the eyeglass frame. The "Pro" mount uses a thin plastic mounting plate that is a 2 3/8" by 1 3/8" oval with four cuts made part way through it. These cuts permit the mount to contour the shape of the rounded side of helmet. The mount has a ball and socket joint independent of the extension arm's so an infinite variation of the mirror position are easily possible. The mount Is self adhesive, on the helmet side, so it will stick and hold to either a soft shell helmet's foam exterior, a hard shell or micro shell helmet's plastic exterior, or adhere to the Lycra cover used over many soft shell helmets. The soft shell model uses Velcro¨ fastening. The "loop" part of the Velcro¨ fabric has a self adhesive back to adhere to the Expanded Polystyrene foam shell. The "hook" part of the Velcro¨ fabric is fastened to an angled plastic mount which suspends the mirror down and in front of the helmet. The mount has a ball and socket joint which operates independent of the holder arm's ball and socket making small adjustments, while in use, possible. Installation for all four models takes just seconds and all three can be mounted and used for either a right or left hand rear view.

THIRD EYE BAR END MIRROR

Third Eye also makes a large convex handle bar end mounted mirror. The mirror is 3" or 76mm in diameter and mounted in a Black molded plastic holder which swivels froward and backward. The mirror holder is adjustable tension bolted to the handle bar mount which is made of molded Black plastic. The handle bar mount uses rubber cylinders that expand inside the handle bar as the mirror holder, on the mount, is turned to tighten the assembly in the handle bar. The bar end mirror comes with two diameters of rubber cylinders so the mirror will work with either thin wall steel or thicker wall aluminum handle bars. Using the large diameter, steel bar set of expanding cylinders the mirror weighs 64 grams, with the small set it weighs 61.5 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...
