Litespeed
Tachyon Tri Road Frame


LITESPEED TACHYON -

This is a Tri-athlete road frame with a 78 degree seat tube angle and vertical dropouts.

The Tachyon (tack-e-on, like tackyon bounce in TNG) Is made from 3Al-2.5V Titanium tubes. The seat tube has been cold worked making a stronger spine for the frame. Made for 650c wheels the wheel base is approiximately 100cm axle to axle.

The shifter bosses, bottle cage bosses, drop-outs, brake bridge, seat post binder assembly and 68mm B/B shell are machined from 6AL-4V Ti plate or rod stock then TIG welded with the tubes.

The Tachyon uses a 1 3/8" clamp-on front derailleur, a 27.2mm post and has external cable routing.

Available in 6 sizes (stand over height) 49cm (71.5) - 51cm (71.5cm) - 53cm (73.8cm) - 55cm (75.7cm) - 57cm (77.7cm) - 59cm (79.7cm). There is also a 61cm size made that has a stand over height of 81.5cm.

This larger size use 700c wheels.

The frame weight averages 3.2 pounds.

To keep its price under $1150, the Tachyon comes a satin Titanium finish only. Very affordable for this type of frame. $ 1139.99

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...
