Grab-on Grips
GRAB-ON MOUNTAIN-1 GRIPSThe Grab-On Mountain-1 grips are a high density neoprene foam grip, superior to imported copies because they are more resistant to ultraviolet ray damage (You've seen how some foam grips crack as the surface dries out). The closed-cell nature of the grips makes it more difficult for them to take an impression (if the grip is leaned against a hard object, cheaper ones leave a permanent mark as the cells collapse). Mountain-1's are round with a small flange at the inner side, and a larger one at the outside, so you can find the bar end while blindly sliding your hand outward. The grip pieces are open at both ends and Grab-On includes two soft plastic end caps that slide over the bar end and under the grip. While there is no provision for wiring on the grips Grab-On includes a packet of adhesive that lubricates the handlebar as it slides on and dries to fasten the grip to the bar. Grab-On MTN-1 grips are available only in Black, weigh with end caps, 118 grams per pair, have a durometer hardness of A/44, and are 5.3 inches long. Made in Washington state, USA. $ Price in Catalog
GRAB-ON MOUNTAIN-2The Grab-On Mountain-2 grip is made of the same closed-cell neoprene foam as are the MTN-1's but they are made in a hexagonal shape to giving your hand six surfaces to grip in the way a clenched hand makes six interior surfaces. The inner end tapers to a small flange from a thick foam palm area. Like the MTN-1 grips they are not made for wire fastening so they come with a packet of their Lube 'N Glue to apply and adhere them to the bar. MTN-2 grips are also opened at both ends and Grab-On includes a pair of soft plastic end caps that slide between the grip and the bar. MTN-2 grips weigh 102 grams per pair, with end caps, have a durometer hardness of A/41, and are 5.4 inches in length. Black only, made in Washington, USA. $ 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... |
