Mirrycle Mirrors
MIRRYCLE MOUNTAIN BAR END MIRROR
The Mountain Mirrycle is a handle bar end mounting mirror with an articulated arm, which permits roll, pitch and yaw adjustments. The mirror element is 3" or 76mm in diameter with a convex face that permits a wider field view. The mirror is mounted in a Black polycarbonate plastic holder that is held to the arm with an hex headed bolt threading into a brass nutsert, permitting it to revolve fully. The arm pieces are molded of Black polycarbonate plastic. Polycarbonate plastic is known to most people under the DuPont brand name of "Lexan". The arm is held into the handle using an expander wedge, like the type used in many stems. The first section of arm which is mounted into the bar end has a 90¡ bend, it is through this bend, from the bar end, the expander bolt that draws up the wedge passes. The expander bolt anchors into a custom, failure-proof, steel nut within the plastic wedge. The second arm piece which the mirror is bolted to also has a 90 ¡ bend with another bolt passing through it, into a brass nutsert, joining the mirror arm section to the bar arm section, again there is complete 360¡ of movement through this joint. The Mountain Mirrycle comes with two expander wedges, each a different diameter to accommodate the wall thickness differences of both aluminum and steel handlebars. The smaller is 6/10" in diameter, the larger is .72" in diameter. The Mirrycle comes with the needed hex wrench for installation, using the small wedge it weighs 101.5 grams, using the large wedge it weighs 104 grams. Mountain Mirrycle$ 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... |
