Archival Review of Suntour Chains
SUNTOUR AP02 CHAINThe Suntour AP02 is the chain used in the Superbe Pro and XC Pro parts Group. It is Accushift Plus and Accushift Plus II compatible, weighing 328.5 grams. It's very narrow having only a 7.3 mm pin width. The AP02 has slightly cambered outer link plates. The pin link plates and the outer link plates have an interior beveling that make this chain a quick, clean, and quiet shifter. The AP02 is all Silver in color and has a hardening treatment performed on the Black pins, and rollers. Made in Japan. No longer made it sold for $24.99
SUNTOUR AP12 CHAINThe AP12 is an AccuShift Plus II and Powerflo compatible chain, that can be used in any 7 or 8 speed shift application. This chain is original equipment for the XC Expert MD, and Road SL parts groups, though it will work on any drivetrain. It weighs a mere 320 grams. The pin link plates and roller link plates have a unique beveling that make this chain a quick, clean, and quiet shifter. The AP12 has slightly outward cambered outer link plates. The pin link plates are Silver and the roller link plates and pins are Black. Made in Japan No longer made it sold for $14.99
SUNTOUR AP21 CHAINThe AP21 is Suntour's least expensive Powerflo chain. It can be used with any of the Suntour parts groups. The outer link plates on this chain, like the other Suntour chains, are slightly outward cambered. This is a narrow 7.3mm pin width chain, that weighs 319 grams. Both sets of plates, and the pins are Black. Made in Japan. No longer made it sold for $11.99 |

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... |
