Fast Feather Quick Release SeatboltFAST FEATHER TI ROD TITANIUM QUICK RELEASE SEATPOST BOLT
Fast Feather is a maker of lightweight, aluminum replacement parts. Their quick release seat bolt is both exceptionally lightweight and elegant in design. The bolt uses an externally visible rotating cam to cinch. The lever handle is anatomically curved to fit nicely in your hand, made of an aluminum extrusion, with graduating holes drilled through it, to reduce weight. The Fast Feather bolt has two machined aluminum spacers next to the cam/lever piece. The one nearest the cam is contoured to the shape of the cam radius and fits with full contact as the lever is closed. The inner side of this piece is convex, and it fits within the concave face of the second spacer. Using the two pieces this way allows the seat bolt to close with no binding and adjusts the angle of the bolt automatically as it's drawn tight. The nut piece is machined from aluminum rod and has six elongated recesses milled away from it's conical shape. The recesses give your finger an easy surface to grip as you tighten the bolt in for the first time. Also on the nut side is an aluminum spacer, which is again convex, that fits into the concave inner side of the nut. This squares up the bolt in your seat lug as it's tightened. The pull-up rod is made of machined Titanium 6Al-4V rod and the anchor piece in the lever is made of stainless steel. The largest distance the skewer will close on is 32mm, the smallest distance it will close on is 3mm. The skewer may be shortened by marking and cutting the extra threaded rod length, then cleaning up the threads with a file afterward. The Fast feather Ti Rod bolt is available with lever, washers, and nut anodized in Blue, Black, Lavender, Silver, or Turquoise and weighs 27 grams. Made in the USA. No longer made, the FF bolt sold for $17.99 |

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... |
