Headset AccessoriesHEADSEALThe Headseal is a piece of neoprene fabric that surrounds the outside of the lower bearing. The stretchy fabric keeps contaminants out of the bearing. It's held in place by tiny stainless steel hooks. The fabric is Black. $ Price in Catalog LIZARD SKIN HEADSET SEALThe Lizard Skin head seal is made of Cordura fabric and surrounds the outside of the lower bearing assembly. The Lizard Skin fastens using Velcroª and comes in 5 colors, Blue, Black, Grey, Lavender or Red. Color-B-BK-GY-L-R $ Price in Catalog
ROCKY MOUNTAIN GORILLA HEADLOCKThis replaces the head lock nut on almost all headsets. The Gorilla headlock uses a principle that some headsets incorporate into their design. Many non-cinching headlock nuts back off the steerer tube threads in use, this device constricts around the steerer tube holding the headset assembly in place. It's made of aluminum, sawn through from one side and partially into the other, providing an expanding or constricting ring. The sawn through portion of the lock is drilled horizontally and tapped for a steel bolt that threads through and draws the pieces together as it's tightened. The interior is tapped for the threads of the fork steerer tube and there is a O-ring recessed at the top to act as a stem seal. The bolt has an allen head and the wrench to tighten the headlock is provided. The Gorilla lock comes in 1", 1 1/8" or 1 1/4" sizes in Silver. The 1" size weighs 39 grams, 1 1/8" is 41 grams, 1 1/4" is 48 grams. 1" size $ Price in Catalog
WHEELS MANUFACTURING GROWLER HEADLOCKThe Growler is machined from 6061-T6 aluminum alloy to replace the non- cinching headset lock nuts provided by the headset makers. The piece is turned on a lathe with a channel milled around the inner surface for an O- ring used as a stem seal. Two parallel cuts create the grip surfaces for the headset wrench. With the threads tapped for the steerer, a hole is drilled horizontally at the base of the headlock nut for the cinch bolt, recessing the head. The cinch hole has threads tapped for the bolt and then cut through to make the cinch mechanism. The bolt has a 3mm hex head fitting. The Growler headlock comes in 1", and 1 1/8" in Silver or Black while the 1 1/4" size comes in Black only. The 1" size weighs 21.5 grams. Color-BK-S 1" size $ 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... |
