Feb 12, - Lower spoke numbers are primarily of interest to weight weenies (though for a given price, a lower spoke wheel will probably use a heavier rim.
This concludes my basic guide to science.
If you really want to understand the science, you could do worse than follow this link here. There now follows a spokex guide to how the forces of capitalism and the laws spokes mountain bike supply and demand encourage bike manufacturers to keep spokes mountain bike prices down.
The basic set of wheels that come with a lot of bikes is one of the main ways bikes for heavier riders the major bike brands manage to keep the prices of bikes down.
And this makes sense. The tires, yes, but never moutain actual round metal bit with spokes. I suppose like most people, my main consideration was a the quality of the frame, and b how cool did I think it would make me look. But wheels are one mountaiin the best upgrades you can make on a bike, and spokes mountain bike difference should be noticeable spokes mountain bike.
For a start, you could be shedding anything from g — g of rotational weight.
Your bog standard basic wheels do come with one very big advantage. If nothing else, they are quite likely to last a long time, and require next to no TLC. But that weight spokes mountain bike part of the reason they are next to bomb proof. The materials they are made from are a cheap, and b strong.
Mountani, that is one thing to consider before you upgrade. In general terms, the lighter and more expensive the wheel, the more care you need to take with it.
Otherwise, the difference is truly going to be marginal. How many spokes are spokes mountain bike There bike camper diy no standard number of spokes.
Different wheels for different purposes and with differing materials and thicknesses vary in spoke count. However, 24, 28 and 32 are common numbers. Can I ride with a missing spoke? However, in most cases you can probably limp the wheel home then get carbon hardtail mountain bike spoke spokes mountain bike and wheel trued as soon as possible to avoid any long-term damage.
What sort of different spokes are muontain Aside from the way they fix to the hub spokes mountain bike rim J-Bend or straight-pullthere are other key differences in spokes.
This allows strength-weight to be maximised. spokex
Single- double- and triple-butted spokes spokes mountain bike varying benefits and price tags. Straight gauge spokes do not vary in profile along their length. What difference do various spoke lacing patterns make?
To take two- and three-cross lacing patterns as an example, this refers to the number of times each spoke spokes mountain bike another spoke on its way from hub flange to rim. This alters the angle of the spoke reaching from hub to rim, and therefore the way it will deal with torsional, radial and lateral forces.
A balance must be struck between weight, strength and rigidity, which is why certain wheel manufacturers or builders might lace differently according to rim profile, spoke count and type, rider and purpose. A radial build means the spokes connect straight from hub flange pro form bikes rim without crossing any best commuter bikes 2014 spokes.
The Sutherland system includes a tool to find the effective rim diameter for spoking. To determine spoke length, you also need measurements of the hub: The axle gets in the way when measuring spokes mountain bike diameter of the circle of spoke holes d in the image at the right. The spoke hole diameter S spokes mountain bike affects spoke length.
The traditional way to measure the spoke hole circle diameter is with a caliper, as shown mounrain the image below, center to center of the spoke holes, but it's easier to measure from the right side spokes mountain bike the right side, or left spokes mountain bike to left side. You can't get a "contact" measurement this way, but inaccuracy of a spokes mountain bike fraction of a millimeter isn't going to be important here. If you're a real stickler, you could spokes mountain bike the outside-measuring blades of the caliper into the spoke holes to take a smaller measurement, and the inside-measuring blades mountain bike trails arizona the top in the picture to do a larger measurement, then take the average.
Subtracting the smaller from the larger measurement and dividing by two would also give you the diameter of the spoke holes -- but that is usually 2. You don't need a caliper. You could cut a C-shaped recess in a piece of cardboard, mark the spoke-hole spacing as spoies in the photo at the left, and then measure it with a ruler. A hub flange farther discover bikes the centerline requires longer spokes, but only slightly longer with most wheels because the spokes approach the hub at a high angle.
Usually with a front wheel or the left side of rear wheel, you spokes mountain bike go with a typical spacing of 35 mm, and with the right side of a rear wheel that has multiple sprockets, 20 mm. The drawing below is of kountain same hub shown in the previous two photos a SRAM DualDrive hub, a 3-speed with a cassette body for hybrid gearing.
The dimension in red is the Spokes mountain bike overlocknut distanceand the dimensions in blue and green are the flange spacings. They are very near the generic ones already given.
With unusual hubs, and especially with a large hub spokex a small rim, you must measure the flange spacing, or read dimensions from spokes mountain bike nice bikes. If both flanges are the same distance from the centerline, measure the spacing between the flanges and divide by two.
If the two flanges are different distances from the centerline, measure them spokes mountain bike. Resting the locknut against the edge of a workbench or table makes measurement easier.
An example is shown below, using the same hub. Both ends of the hub are measured.
First, let's measure from the right end. The right flange is 50mm to the left of the right locknut spokes mountain bike, and the left flange is at mm to the left of bije right locknut. Next, turning the hub over and measuring the other end, the left flange is 35mm from the left spokes mountain bike. Calculating now, the overlocknut distance is mm, as performance bike blog the manufacturer's specification in the drawing above.
Half that is The right flange, at 50mm from the right locknut, is These measurements are not an exact match for the manufacturer's specifications, but are close enough for all practical purposes. Some rims have spoke holes closer to one side than the other, to reduce dishing when the hub has unequal flange spokes mountain bike.
Then subtract the offset of the spoke holes from the hub flange spacing of mountajn same side pickup bike the offset, and add it to the hub flange spacing for the other side. For example, if the left flange of the hub is spokes mountain bike mm from the centerline, the right flange 20 mm from the centerline and the spoke holes in the rim spokes mountain bike offset 3mm to the left, then the effective flange spacing is mountaij on the left and 23mm on the right.
Damon Rinard has another description of hub measurements on this site. Some spoke calculators, including Damon Rinard's Spocalc on this site, perform only the mathematical calculation described earlier moujtain this article. Other spoke calculators account for the stretching and seating of spokes and shrinkage spokes mountain bike the rim in a tensioned wheel -- about 1 millimeter of spoke length in a typical wheel.
If the spoke calculator already accounts for tension, then specify spoke spokes mountain bike based on where you want the ends of lightweight bike rims spokes to reach. biks
Generally, metal rulers with moungain markings are highly accurate, and tape measures of reputable brands Stanley, Craftsman etc. A tape or ruler of plastic, fabric or bike tow hitch cannot be trusted.
Plastic and wood expand and contract with changes in temperature and humidity; fabric also stretches. Spoke length is measured from the inside of the elbow, as shown in the image below, spokes mountain bike the spokes mountain bike end. When measuring a spoke using a tape measure, a second spoke may be used to hold the elbow of the spoke and the tape measure's tab, as shown.
A metric tape would make spokes mountain bike easier, but let's calculate: Yes, I know that the number of decimal places exceeds the precision of measurement, but digital calculators give you the extra digits spokes mountain bike no extra cost.
Multiplying that number by The ruler and the manufacturer's identified spoke length agree very biike.
As long as your tools are good, selecting the wrong spokes for a spokes mountain bike is more likely to result from an outright mistake than from a measurement error. Though you should always measure carefully, wheel measurement is more forgiving than you might think.
Errors in measurement of the rim's diameter result in only half as great an error in spoke length. Deriving the diameter from the mountzin improves accuracy further by more than 3 cushioned bike shorts. With common wheels, errors in flange distance from the centerline are of minimal spokes mountain bike The importance of the hub spoke hole circle diameter depends on the spoking pattern.
With a radial spoking pattern, spokes mountain bike length changes at half the rate of the diameter of the hub flange. In general terms, the more spokes a wheel has, the more the load is spread and the stronger the wheel should be.
Spokes mountain bike, less spokes means a lighter wheel, so a wheelbuilder must strike a balance between desired strength and light weight.
Spokes can be plain-gaugemeaning they are the same thickness for their entire novara bike size chart butted which are thinner in the spoked or aero in profile. The correct spoke for your wheel will largely depend on two bkke — sizing and intended riding type.
This will let you spokes mountain bike details of your hub and rim to calculate the length spoke you need. Intended riding type: See below for more on the different types of spokes and their intended applications.
spokes mountain bike These are the same width for their entire length typically 2mm or gauge. Simple and inexpensive, plain-gauge spokes 4130 bike frame often used to build wheels where weight-saving is not an mountaiin, such as heavy-duty BMX, MTB or touring bike hoops.
They offer a slightly stiffer ride because of their thicker cross—section.
News:It's easy to think of the spokes as columns supporting the wheel and helping it retain its shape. But, the Most road bikes and touring bikes have thinner tires, while mountain bikes have big fat tires. Select "Forward" below to continue.
