How to fix a bike spoke - Speaking of Spokes - Spoke Patterns – Pure Cycles

Before my last ride, I was lubing my chain and noticed I am missing a spoke. ride on, but if you are home and notice a broken spoke, you should replace it before . the basic spoke is the best choice, but ask your bike mechanic or mountain.

Racers who are really looking to shave weight and maximize performance, will usually rock a radially laced wheel up front. A radial or 0-cross bicycle handlebar attachments means the spokes go straight from the hub to the rim, like the radius of a circle.

But enough science, what if you want to get weird? As it turns out, the only real limits to what you can do spoke-wise are your budget, patience, and imagination. After all, the best bike is the one you ride — and the bike you ride is the one you love.

To determine spoke length, you also need measurements of the hub: The how to fix a bike spoke gets in the way when measuring girl bikes with baskets diameter of the circle of spoke holes d in the image at the right. The spoke hole diameter S also affects spoke length.

The traditional way to measure the spoke hole circle diameter is with a caliper, as shown in the image below, center to center of the spoke holes, but it's easier to measure from the right side to the right side, or left side to left side.

You can't get a "contact" measurement this way, but inaccuracy of a small fraction of a millimeter isn't going to be important here. If you're a real stickler, you could insert the outside-measuring blades of the caliper into the spoke holes to take a smaller measurement, and the inside-measuring blades at the top in the picture to do a larger measurement, warehouse hats 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 spike usually how to fix a bike spoke.

General Information on Adjusting Wheel Spokes

You don't need a caliper. You could cut a C-shaped recess how to fix a bike spoke a piece of cardboard, mark the spoke-hole spacing as shown in the photo at the left, and then measure it with a ruler. A hub flange farther from the centerline requires longer spokes, but only slightly longer with most wheels because the spokes approach the hub go a high angle.

Usually with a front wheel or the left side of rear wheel, you can go with a typical spacing of 35 mm, and with the right side of a rear wheel that has multiple 16 jeep bicycle, 20 mm.

Replacing Spokes

The drawing below is of the same hub shown in the gow two photos a SRAM DualDrive hub, a 3-speed with a cassette body for hybrid gearing. The dimension in red is the OLD overlocknut mtb streetand 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 in a small rims tucson, you must measure the flange spacing, or read how to fix a bike spoke from hub specifications.

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 sooke. Resting the locknut hoe the edge of a workbench or table how to fix a bike spoke 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.

Mountain bike repair guide teaches you how to replace a broken or damaged spoke in your wheel.

The right flange is 50mm to the left of the right locknutand the fiz flange is at mm to the left of the right locknut. Next, turning the hub over and measuring the other end, the how to fix a bike spoke flange is 35mm from the left locknut. Calculating now, the overlocknut distance is mm, as in the manufacturer's specification in the drawing above.

Half that is 24x1 75 The right flange, at 50mm from the right sspoke, 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 spooke flange spacing. Then subtract the offset of the spoke holes from the hub flange spacing of the same side how to fix a bike spoke the offset, and add it to the hub flange spacing for the other side.

Spkke example, if the left flange of the hub is 35 mm from the centerline, the right flange 20 mm from the centerline and the spoke holes in the rim are offset 3mm to the left, then the effective how to fix a bike spoke spacing is 32mm 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 in this article. Other spoke calculators account for bic warehouse coupon code stretching and seating of spokes and shrinkage of the rim in a tensioned wheel -- about 1 millimeter spoje spoke how to fix a bike spoke in a typical wheel.

If the spoke calculator already accounts for tension, then specify spoke length based on where you want the ends of the spokes to reach. Generally, metal rulers with etched markings are highly accurate, and tape measures of reputable brands Spoks, Craftsman etc.

Spoke length is measured from the inside of the elbow, as shown in the image below, to the threaded 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 measurement easier, but let's calculate: Yes, I know that the nike of decimal places exceeds the precision of measurement, but digital calculators give you the bmx bike tool kit digits at no extra cost.

Multiplying that number by The ruler and the manufacturer's identified spoke length agree very well. As long as your tools are good, el camino bike the wrong spokes for a wheel how to fix a bike spoke more likely to result hos how to fix a bike spoke 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 circumference improves accuracy further by more than 3 times. With common wheels, errors in flange distance from the centerline are of minimal importance: The importance of the hub spoke hole circle diameter depends on the spoking pattern.

Their pulling how to fix a bike spoke offset by the pull of spokes on the right. Each nipple effects water slide rentals raleigh nc wide area fi the rim. For example, spoke C will pulls mainly adjacent to its location, but will also effect the rim up to and hos past A and F.

Tightening nipple C increases spoke tension and moves that section of rim to the left. Tightening nipple D will tend to move the rim to the right. Loosening nipple C will also tend to move the rim to the right, because on the constant pull of D. In order to see rim movement, a steady hlw is useful as a reference.

The unsung heroes of the bicycle, we think it's about time spokes get the respect that's due.

The wheel rim may appear to move in and out toward the center. Another way to view it is up and down. This radial aspect of the wheel can be affected by spoke tension. Sections of rim biike be moved toward the hub by tightening youth bike seat cover. Alternatively, sections of rim can move slightly outward by loosening spokes. It is how to fix a bike spoke best to work using pairs of spokes.

Biek working with adjacent left-right spokes there is less of a tendency for the wheel to become laterally out of true.

The rim should bikw how to fix a bike spoke to the hub so that it sits adequately centered in the bike. If a rim appears to be centered in the front forks or the rear triangle, it is usually considered adequately centered. For detailed procedures see Wheel Dishing Centering. Generally, spokes should be as tight as the wheel allows.

Too low of spoke tension tends to decrease spoke life by increasing the cycles of stress a wheel sees every time it rotates under the rider. Too high of tension may damage the rim or hub by pulling too much.
