What ishardness

The Contour Handlebar is ProTaper’s most popular model. Oversized-diameter handlebars without crossbars were invented and patented by ProTaper in 1991. Without sacrificing strength, this design yields increased flex and impact absorption over conventional handlebars, offering the rider improved comfort and reduced fatigue. With its 2000 series aluminum alloy construction and computer-profiled 5 mm-thick wall design, the Contour Handlebar is up to 20% lighter and 40% stronger than competing handlebars. At only $149.95, it’s also the most affordable way to equip your bike with the 1⅛” handlebar design that changed an industry.

Hardness testing enables you to evaluate the strength, ductility and wear resistance of a material, which can determine whether a material is suitable for the purpose you require. The hardness of a metallic material can be defined as its resistance to plastic deformation caused by a force applied through an indenter. It is an unusual property in that it is the result of a defined measurement procedure and not an intrinsic property which can be defined in terms of fundamental SI units.

Vickers hardness test: A diamond indenter, in the form of a square-based pyramid with an angle of 136º between the opposite faces at the vertex, is pressed into the surface of the test piece using a prescribed force and, after the force has been removed, the diagonal lengths of the indentation are measured. The time for the initial application of the force is 2 s to 8 s, and the test force is maintained for 10 s to 15 s.

If there’s one thing I know it’s handlebar bends. Most buyers on here are looking for a bar to suit enduro/trail riding or adventure/general riding. The standard bars on most of the old school bikes are useless, steel, heavy, with a low bend and too much sweep.

In our opinion we stock the three best, the Windham/RM Mid, KX High and Pastrana FMX High all in by far the most popular black ! If using high bar risers or the highest of bars you may need to reroute your cables subject to what bike you own.

NOTE – highly recommend adding the best heated grips, US Symtec Heat Demon Heated Grips at the same time, clearly listed under ‘lighting/electrical’ you’ll thank us for that advise

The determination of a hardness value depends on many different parameters, such as force, diameter, depth, time, radius, and angle. Each of these measurements has an associated uncertainty, and these uncertainties will each contribute to the overall uncertainty of the hardness value. The sensitivity coefficient relates the uncertainty associated with the parameter and the uncertainty of the hardness value. Sensitivity coefficients can also be used to make corrections to hardness values in situations in which the measured value of an input parameter differs from the value specified within the relevant standard or, where a range of values is permitted within the standard, to correct the hardness to a nominal input parameter value.

NOTE – no you do not need to get longer cables made !! most reroute their cables to free them up giving additional length

NOTE – DR/DRZ riders pays to add a new throttle tube at the same time of purchase, select your choice of grip and add some grip wire, you’ll find them listed under the same category ‘controls’

Below is an example of the useless bars that came on these older style trail and enduro bikes, old heavy steel, too low, too much bend, bin em !

Commonly referred to as Tapered Bar or Fat Bar, these are 1 1/8″ and yes ALL handlebars are 7/8″ inch measurement at the grip end !

Brinell hardness test: A ball indenter of diameter is pressed into the surface of the test piece using a prescribed force, and the diameter of the indentation is measured after the force has been removed. The time for the initial application of the force is 2 s to 8 s, and the test force is maintained for 10 s to 15 s.

Hardnessof materials examples

In practice, hardness is measured in terms of the size of an impression made in a specimen by an indenter of a specified shape when a specified force is applied for a specified time, the indent being measured after the force has been removed. The three principal standard methods for expressing the relationship between hardness and the size of the impression are Brinell, Vickers, and Rockwell, each of which has a range of scales defined by a combination of applied load and indenter geometry.

Rockwell hardness test: Either a 120° diamond cone with a 0,2 mm radius spherical tip or a ball indenter of a specified diameter is pressed into the surface of the test piece using a two-step application – a preliminary test force F0 followed by an additional test force F1. The preliminary test force is applied and maintained for a duration that does not exceed 3 s and an indenter depth reading is recorded. The increase in force to the total test force F then occurs in between 1 s and 8 s. This force is maintained for a duration of 4 s ± 2 s, and the additional force is then removed. While the preliminary test force is still applied, a second indenter depth reading is made after a short stabilisation time.

NOTE – Handlebar dimensions are within the images and suit a large range of riders from little blokes like me with short reach to the tallest with long reach.
