SRP Front Derailleur Bolts
SRP TITANIUM FRONT DERAILLEUR CLAMP BOLTSRP also makes a Titanium alternative to the stock clamp fastening bolt that comes on front derailleurs. This is the bolt that holds both clamp halves together, binding it to the seat tube. The bolt is machined of Ti 6 Al-4V rod like the cable fastening bolt. It has 5mm x .8mm thread pitch, with a thread length of 14mm. The top of the head is broached with a 5mm hex head for easy installation. This bolt replaces all front clamp bolts used on the Mavic, Shimano or Suntour models, weighs just 2 grams, and is made in USA. A longer model having an 18mm length, originally intended for water bottle braze-on use with a 4mm hex head, we found works quite well for braze-on mounting of the Campy Record front derailleur. This longer bolt also weighs just 2 grams. 29-91-CB 5mm x .8mm x 14mm $ Price in Catalog
SRP TITANIUM FRONT DERAILLEUR CABLE FASTENING BOLTThis is the bolt that cinches the front derailleur shift cable to the front derailleur. SRP machines it from Ti 6 Al-4V rod, then broaches the top creating a 5mm hex head for tightening, then rolls the threads into the bolt. The threads are 5mm x .8mm thread pitch and 8mm long. It will replace all cable fixing bolts on the Mavic 860, 862, 875, the braze-on mounting bolt used on the Mavic 862, and the clamp bolt on the Mavic 875. It will fit work with all Shimano or Suntour front derailleur. The 8mm long version weighs 1.5 grams, USA 29-91-FB 5mm x .8mm x 8mm $ 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... |
