Suntour XC Pro SeatboltSUNTOUR XC PRO SEATPOST BOLT
This is a well crafted bolt, using steel parts where needed for strength, and aluminum everywhere else for weight reduction. The lever and inner cam piece are a single steel casting, which is bent at the point where it exits the cam assembly. Wisely Suntour has this pass totally through the aluminum cam housing, using a hole in the far side as the pivot anchor. The lever piece is painted black with a firm plastic Black sleeve in the area of finger contact. The cam housing is machined aluminum alloy, anodized Black. A spring and aluminum washer on the cam housing side provide a flush surface and equalize the tension as the lever is tightened. The nut is machined aluminum alloy anodized Black, with a plastic insert to prevent it from loosening up, mounted in the outer side. The nut also has a recess built into it for the flat surfaced O-ring that provides fingertip grip while fastening. The largest distance the XC PRO seatpost bolt will close on is 37mm, the smallest distance it will close on is 18mm. The skewer may be shortened by marking and cutting the extra threaded rod length, then cleaning up the threads with a file afterward. Weighing 54 grams, the Suntour XC PRO bolt is available only in Black. Made in Japan. No longer made, we sold this for $14.99 |

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... |
