Light Speed Bar Ends


LITESPEED TITANIUM BAR ENDS

Litespeed uses Ti 3Al-2.5V Titanium tubing as the raw material for their L-bend styled bar ends. The cinch assembly is made from 1.4mm wall thickness tubing cut to provide a 1 1/4" width on your handlebar. The cinch fitting is machined from Ti 6Al-4V rod, turned on a lathe to reduce the center diameter and bring the width down 10mm so the cinch bolt will fit squarely and flush. The bolt piece is drilled and tapped with the 6mm by 1mm pitch bolt threads, then TIG welded to the bottom of the cinch assembly.The grip tubing is made of .8mm wall thickness Titanium tubing, with an overall length of 8 inches. The grip tubing is miter cut to contour the cinch tube then the two are cleanly TIG welded together. The grip tubing rises from the cinch assembly at a 15 degree angle, while also sweeping inward toward the front wheel at a 15 degree angle. At 3 1/2" from the cinch tube, a bend creates the secondary grip section that turns at an added 65 degrees inward. With the grip tube welded in place the cinch fitting is welded to the bottom of the cinch tube, then the cinch tube is sawn through to make the clamping mechanism. The bolt has a 5mm hex fitting, is made of Ti 6Al-4V Titanium alloy, and has a weight of 3.5 grams. It is a 6mm by 1mm pitch with a 20mm length. The Litespeed bar ends come with two of the Rodon press-in plastic caps we mentioned in the overview, installed in the end of the grip tube. Two more to fit in the end of the handlebar are not provided. The pair of the Litespeed bar ends, with the Ti bolts and Rodon caps weighs 140 grams. These are no longer made. We sold them for $89. 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...
