SRP Titanium Replacement Bolts


SRP TITANIUM SADDLE FASTENING BOLT

This is a Titanium replacement bolt for the micro-adjusting seatposts using an 8mm by 1.25mm thread pitch that is 41mm long. It takes the standard steel bolt, that weighs 21 grams, and replaces it with a 6mm allen head Titanium bolt that weighs just 10 grams. It is a direct replacement for the fastening bolts found on the Mavic 337, SR Laprade, SR TCO, SR TCO Sport, Ritchey Pro, Ritchey Comp, Kalloy Aluminum, Kalloy Cro-moly, and Tioga Carbo posts.

SRP TITANIUM XTR/XT/DX & CAMPY RECORD

SEATPOST FASTENING BOLT - SOLID AND HOLLOW

These are made as a direct Titanium replacement for the Shimano XT, an indirect replacement XTR and, if you ever see any, the Dura-Ace Aero post, and the now discontinued Deore DX seatpost. The bolt is made of Titanium 6Al-4V rod with an 8mm by 1mm thread pitch. The solid bolt (18-91-834) is 34 millimeters long, while the hollow version is 29 millimeters long. Both can really be used interchangeably, though nominally the hollow bolt is for the XTR post. The original steel ones these replace weigh 18 grams. The SRP bolts having a 6mm hex head weigh just 9 grams in the solid version and 5.5 grams in the hollow version. A final model also solid is made, and can be used in the Campy Record post. This bolt is 8mm by 1mm thread pitch, 41mm long and solid. It weighs 11 grams in the Titanium version instead of 17.5 grams in the steel version. The added two millimeters over the original Campy bolt are negligible and do not impair performance.

SRP TITANIUM 6mm x 1mm CLAMP FASTENING BOLT

The bolt is made of Titanium 6Al-4V rod with a 6mm by 1mm thread pitch, and is available in a 20mm, 25mm, 33mm, 45mm, or 55mm length. The 20mm length weighs less than 3 grams and replaces the bolts used on the Control Post, Mountain Goat, Kona, or the MRC post. The 33mm long bolts weigh just under 5 grams, and replaces the steel clamping bolts, weighing 8 grams, in the American Classic, Kingsbery, ARR - Gordon and RinglŽ. We are also including two additional lengths for which we know of no present seatpost application though you may have a separate interest. The 6mm by 1mm with a 45mm length has a weight of 6 grams. There is also a 6mm by 1mm with a 55mm length weighing 7 grams.

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...
