Sachs / Sedisport Chains
SACHS/SEDISPORT SC-30/40 CHAINSachs/Sedisport chains are the industry standard for replacement chains, and are the one most recommended to people by our service department. They work with all freewheels and shifting systems. The link pins are 7.29mm long making the chain narrow enough for all 7 or 8 speed applications. The link plates and the roller plates on the SC-30 are Black steel. The Delta treated pins reduce stretching and breaking. The inner surface of the roller link plates are beveled to insure smooth, quick shifting. Weighing 340.5 grams, it has 116 links and comes in three colors: Black, or Silver, (which has a nickel finished). Black $ Price in Catalog
SACHS/SEDISPORT ATB / SC-M50/55 MOUNTAIN-BIKE SPECIAL CHAINThis is the single most recommended chain. It works universally well with any shifting system is smooth, efficient, and serviceable without special pins. It offers simplicity and ease in an area of the bike made too complicated by others. The Sedisport ATB has Delta treated pins, with the inner surfaces of both plate types beveled. The outer plates are nickel plated giving them a Silver color, the roller plates are Black. The link plates, in the pin area, narrow in thickness as they move to the vertical edges. Made in France, the SC-M50 has 116 links and weighs 339.5 grams. This Silver/Black chain will work with any shift system, including Hyperglide! Price in Catalog
SACHS/SEDIS PRO SL / SC-R80 CHAINThe Sedis Pro is the Professional version of the Sedis chains intended for use on road racing bikes or mountain bikes requiring a high quality, narrow, replacement chain. It has 114 links, perfect for all road applications and compact/micro mountain bike use. The Pro chain has the beveled outer link plates, and pins that are just 6.99mm long, to work with all indexing shift systems. The chain is nickel plated to give it a Silver color, and heat treated on all chain parts. The nickel plating helps prevent rust. This is the chain Campagnolo ships with their grouppos, and Mavic ships with their part grouppos. Made in France, it weighs 317.5 grams. Price in Catalog |

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... |
