Brake Levers


TECH LITE LEVERS

The Tech Lite lever set is the light weight winner. The Tech lever uses a traditional non-compound pulling action. The clamp piece is made of machined 6061-T6 aluminum, with two clamping bands. Each of the bands has a small recessed cap bolt that spans a 5mm gap anchoring into the opposing side. As the bolt is turned the 1.15mm thick clamp tightens onto the handlebar. The cap bolts are made of stainless steel and have a 2.5 mm hex fitting.

The middle of the clamp assembly is machined away so the handle piece can be mounted inside the clamp housing. The lever is machined from 1/4" thick aluminum plate. Mill work in the clamp area reduce the handle weight. A coiled spring has one end bolted to the handle with the other end hooked around the clamp tightening bolt nearest the stem. This is the lever return spring and pulls the lever closed when released. The cable convenience adjuster is machined from aluminum with 5mm by .8mm threads. The side of the adjuster isnÕt cut through so threading a new brake wire will take a little longer. There is also no fixing nut, instead there is a rubber washer to hold the adjuster's position.

The handle is covered with a Black foam rubber sleeve that builds out its shape and cushions the riders grip. The Tech Lite levers have no reach adjustment. The area for finger grip is 80mm long. The clamp piece comes anodized in Blue, Black, Lavender, or Silver. The handle piece is always Silver. The weight of the Tech Lite levers is 106.5 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...
