Crystal Design Bar Ends
CRYSTAL DESIGN QUICK GRIP BAR ENDSCrystal Bar Ends are an economical, all aluminum, straight bar end using cinch fastening. The cinch section is made of an aluminum extrusion cut to 1 3/8" length, (which will become "width" on the handlebar). The cinch extrusion is bored front and rear for the two steel cinch bolts. Two steel nutserts are pressed into the rear of the extrusion, so the steel bolt threads into a mated steel nut. The extrusion is cut through lengthwise to create the clamping mechanism. Two 4mm x .60mm bolts, that are 10mm long are used to tighten each Quick Grip. The aluminum grip tube has a wall thickness of 1.7mm, is four inches long, and straight. The grip tube is miter cut to contour the cinch assembly, then TIG welded, at a 9 1/2 degree angle, from straight ahead, to the cinch assembly. The entire bar end is electrostatically (powder) painted a glossy Black. Two Black plastic end plugs for the grip tubes are included. These bar ends a great value, with beefy welding. A pair of Crystal Designs bar ends, with end plugs, weighs just 125.5 grams. Made in Colorado, USA. No longer made, these sold for $23.99 a pair.
CRYSTAL DESIGN QUICK GRIP PLUS BAR ENDSThe Quick Grip Plus is the L-bend version of the Quick Grip. The Plus model uses the same cinch assembly as the Quick Grip, with an 8 inch long tubing grip section made of the same aluminum tubing. The grip section is welded to the cinch assembly at a 12 degree angle, from handlebar perpendicular, inward toward the front tire. The grip tube is bent further inward at the 4 inch mark adding 70 degrees more of bend to the aluminum tube. They are electrostatically painted glossy Black. The pair with end plugs weigh 182.5 grams. Made in USA.No Longer made these sold for $23.99 a pair. |

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... |
