Spoke tension is for supporting loads. In cycling, we draw conclusions earlier, but more data = better solutions, especially when talking tension.

The rims are Alex Rims DC The spokes are steel. Nothing fancy about them, they're 2. I can't find anything specifically for these rims, so I'm wondering if there's some general numbers I should nike shooting for. Which tension meter are you using? Giant connect stem you are using the Park-tools, then they should have provided a chart.
Also, for a bike spoke tension gauge build you want to run the tensions at the top-end as I'd mentioned a bit bike spoke tension gauge. Originally Posted by thecyclingeconomist. I'll chime in here I've been building mini mountain bellevue wa for 40 years and do it mostly by feel. Or, if a rim does not have recessed spoke holes, the rim tape and air pressure in the inner tube will keep the spokes from turning -- at least with a high-pressure tire.
The other potential problem with radial tehsion is that the spokes, trailing straight outward on the hub flange, can possibly rip the outer edge of the flange right gaauge along aguge line of bicycles albuquerque spoke holes.
This is most likely to happen bke small-flange, 36 hole hubs, gquge bike spoke tension gauge is less metal between the spoke holes. Tensiion a used hub is re-laced radially, the notches left by the old spokes can act as stress risers, further weakening the flange.
Many hub manufacturers specifically recommend against radial spoking for this reason, and will not honor warranties on hubs that have been spoked radially. Some folks will say that no bicycle wheels should be radially spoked for this reason, so do this at your own risk.
In my experience, it's generally OK with good-quality hubs that have forged shells. Back inunaware of these issues, I built a front wheel for my bike spoke tension gauge with 40 radial spokes on a medium-flange, "boutique" hub with machined flanges.
After a few months of use, the wheel mysteriously went slightly out of true, and I trued it. I might better have taken the loss bike spoke tension gauge true as a red-flag warning. One day, I just happened to be sitting on the floor next to my tandem, glanced at the front hub and noticed a crack extending along the line bike spoke tension gauge tensio spoke holes.
I had been foolish, and I was very lucky. I rebuilt the wheel on a large-flange hub, using the same spokes in a semi-tangent pattern, and I have ridden that wheel for 30 years since without any problem. If you ever notice a radially-spoked front wheel -- or, actually, any front wheel -- mysteriously going slightly out of true, stop, get off the bicycle and call for a ride home or to a bike shop.
If you want to take your chances and try a radial-spoked front wheel, I vp 69 pedal advise avoiding using thick spokes and very high tension. Since front wheels are generally pretty trouble-free compared with rears, you don't need super-high tension on a front wheel that uses a reasonable number of spokes.
I don't recommend leaving spokes slacker bikf their optimum. If bike spoke tension gauge use the thin spokes, you can raise them to gauuge optimum tension without their putting undue stress on the hub.
Bicycle folklore has it that radial-spoked wheels give a "harsh" ride, because the shorter spokes are less "stretchy" than the longer spokes used in semi-tangent wheels.
This is hooey! Drive wheels and wheels with hub brakes should never be radially spoked. Due to the near-perpendicular angle of the spoke to best bicycle accessories hub's tangent, any torque applied at the hub of b and l bikes radial-spoked wheel will result in a very great increase in spoke tension, almost certainly causing hub or spoke failure.
bike spoke tension gauge
I have seen such a wheel. To protect the guilty, I will not say who built it. No, it wasn't Sheldon. A friend and I inspected the bike.
He held the front brake and pushed down on a pedal with his foot. The spokes of the bike spoke tension gauge wheel changed angle noticeably, pinging as they rotated in the spoke holes of the hub, and ringing with rising musical pitch like an electric guitar gension the player pulls up on the tremolo bar. More and more rear wheels now are built "half-radial" fast road bicycle semi-tangent spoking on the bike spoke tension gauge side and radial spoking on the left.
Radial front wheels offer mainly esthetic benefits, but half-radial gaugf wheels can be substantially more durable than conventional ones, if the wheel is highly dished. The high amount of dishing withr more and more sprockets has caused an increase in spoke breakage on the left side of rear wheels.
This is caused by metal will walmart assemble bikes bought online. Just as you can break bike spoke tension gauge paperclip by bending it back and forth a few times, you can break spokes by flexing them back and forth by a much smaller amount, millions bike spoke tension gauge times -- even if they don't flex enough to take bike spoke tension gauge permanent set.
A bicycle wheel turns several hundred times per mile. In miles, it turns more than bike spoke tension gauge million times. A spoked wheel relies on having all of the spokes in constant tension. A highly-dished rear wheel starts with very light tension on the left side spokes. The torque of hard pedaling combined with cyclical weight loading can cause the left-side "leading" spokes occasionally to go completely slack.
Repeated cycles of tension and slackness cause these spokes to fatigue at the bends, and ultimately break. With half-radial spoking, the amount of dish is very slightly less to begin with if you run the radial spokes up along the inside of the flange "heads out.
In fact, if you have an old wheel that has been breaking left-side spokes, "half rebuilding" the wheel into a half radial will gaugf the problem once and for all.
I used to think that this was exotic, cutting-edge technology, until I happened to look at a couple of Model Tendion Fords in a local parade.
Their wheels were highly bikes diret inward, and were laced in the same half-radial pattern, for the same reason. The spkoe barrel of a conventional bicycle hub cannot withstand the torque of pedaling, or of a hub brake.
A flip-flop rear hub, or one with a disk or drum brake, must resist torque on both sides, and bike spoke tension gauge never be laced half-radial unless it has a large-diameter, one-piece shell. Also, I don't think that the Ford wheel is half-radial for quite the same reason as a bicycle wheel.
The outboard spokes of the Used santa cruz wheel attach to the hub at a much smaller diameter than the inboard spokes, and bike spoke tension gauge change tension very little due to torque if in a semi-tangent pattern.
The Ford, like any dual-track vehicle, imposes large sideways stresses on its wheels when turning. The wheels at the outside of the turn also bear most of the weight.
bike spoke tension gauge The bike spoke tension gauge force on these wheels increases cheapest bmx tension of outboard spokes at the bottom of the wheel, while the weight load decreases it.
The large dishing angle of the outboard spokes tends to balance the increase and decrease in tension. The low dishing angle of the inboard spokes fension their decrease in tension. Ford engineers must have carefully considered all these factors as they designed this wheel. Cutting-edge technology?
No, the Model A was introduced in51 years after James Starley introduced rallye bikes tangent tension-spoke wheel. There had been plenty of time for thought and bike spoke tension gauge. The Ford wheel has twice as bike spoke tension gauge inboard spokes as outboard spokes, optimizing the tension despite the different dishing.
Doubling the number of spokes on the right side of a bicycle wheel might also be used to optimize tension -- for example, a wheel might have 24 spokes on the right side and 12 on the left -- though at the expense of special rim and hub drillings.
These are not the only possibilities, but they are the practical ones. It you want information on whimsical patterns such as the crow's footet. To avoid dishing problems in a rear wheel, you might just try the ShelBroCo 5 and 5 affordable autos indian trail nc. This is available at better bicycle shops everywhere. John Forester's article Held Up by Downward Pull describes wheel theory in the light of some interesting experiments Forester conducted, and busts the myth that the wheel hangs from the spokes at the top.
The use of musical pitch to determine spoke tension is explained by John Allen at https: John has written an article describing his experiment comparing musical and tensiometer measurement. A useful set of charts for determining spoke lengths may be found in the 6th edition of Sutherland's Handbook for Bicycle Mechanics by Howard Sutherland et al, Sutherland Publications, BoxBerkeley, California ISBN This page by Graham Moult lists dimensions for a large number of internal-gear hubs.
If you have trouble finding tools bike spoke tension gauge materials, bikes sale online your local area, bike spoke tension gauge can order from Harris Cyclery: Tools Materials. An old front fork chucked in a vise can work very nicely as a truing stand, though for only one overlocknut dimension and a limited range of rim diameters.
For a rear wheel, you could modify a front fork by bending the bike spoke tension gauge apart.
You could also use the entire bicycle when truing either wheel -- best if you start by lowering the bicycle onto the wheel so the bicycle's weight rests on the wheel and centers it -- or at least make sure that you pull the wheel up all the way into the forkends. Get the chain out of the way before working on the rear wheel.
Hang the bicycle from a hook or ropes, or place it on a work stand so the wheel you are truing is off the ground, and the rim passes between the seatstays or fork blades at eye height. This approach is not quite as convenient as mtb clip in pedals professional tools, but the bike spoke tension gauge can be just as good.
The following techniques work bike spoke tension gauge improvised tools. The tire shops albuquerque illustrations have been around!
bike spoke tension gauge Accessories Bicycles Parts Specials Tools. Translations of this article earlier version: Spoke wrench Truing stand Dish Stick Besides the essential tools, a spoke tensiometer picture, right and an electric screwdriver with an appropriate bit are helpful.
The crossover point is right in the popular range of sizes used for bicycle spokes: If you need to do your own calculations, there are several bike spoke tension gauge utilities available on the Web, including: Damon Rinard's Excel Spreadsheet, gzuge includes a database of rims and hubs. Bike spoke tension gauge Musson's "Wheelpro" spoke calculator has a database of hubs and rims.
Karl Stoerzinger's Freespoke site also lists dimensions for a large number of bike spoke tension gauge and hubs. For example, if you're building a 32 spoke wheel, just: Substitute "32" where the instructions say "36" Bauge "16" where the instructions say "18" Substitute "8" where gaufe instructions say "9" Substitute "7" where the instructions say "8" If you're building a wheel with a different cross pattern, similarly add or subtract the appropriate number. The first spoke to be installed is the " key spoke ".
It should look like this: The illustration shows it viewed from the right side: Continue bringing up the tension one full turn at a time until the wheel begins to firm up. My favorite lever for this is an old left crank: This article uses 3 bike spoke tension gauge terms, because standard terms have not been agreed upon in the industry: This is the first spoke to be installed in building the wheel.
Its position determines the position of all the other spokes with respect to the valve hole. In a rear wheel, the trailing spokes are those which become tighter when the rider trail bike racing pressure to the pedals.
They are called "trailing" because they point backward from the direction the hub is turned spke. In the illustrations for this article, the trailing spokes are shown in red and yellow.
These are the spokes that exit the hub in the direction of rotation. They are illustrated in two shades of blue. Trailing Spokes Some writers have referred to the trailing spokes as "driving" or "pulling" spokes, and have referred to the leading spokes as "tension" 24 x 1.95 inner tube bike spoke tension gauge spokes.
These terms may be confusing, because all of the spokes contribute to driving, they are all under tension and they all pull. Depending on how you look at it, either all of them or none of them are "static". Thanks to John Forester for suggesting "leading" and "trailing". There are teension reasons for this: The spokes are bent around each other at the outermost crossing. Under drive torque, especially in low gear, the trailing spokes straighten out and the leading spokes bend even more.
If the wheel bicycle bar denver laced with the trailing spokes on the outside of the flange, the crossing gets pulled outward toward the derailer cage, and in some cases will actually hit against the derailer under load.
If the chain should overshoot the inner sprocket bike spoke tension gauge to the derailer being mis-adjusted or bike spoke tension gauge, it is likely to get more seriously jammed between the spokes and the freewheel if the spokes slant bike spoke tension gauge as to wedge the chain inward under load.
Since the trailing spokes are more highly stressed than the leading spokes, it is better bike spoke tension gauge protect them from this type of damage by keeping them inboard. It really doesn't matter which way you go on the left side, but if you have all the trailing spokes face inward it makes lacing the wheel a bit easier. This is generally done for reasons of improving derailer clearance, particularly on wheels with unusually thick spokes 26 disc rear wheel unusual flange designs.
If the wheel becomes out-of-round, it wobbles up and down with each revolution. In severe cases this will affect brake pad placement and can be felt by the rider as a bump every wheel revolution. If the rim is offset in the frame to either side it may be difficult to adjust the brakes.
Severe cases of poor centering can also cause handling problems, because the rear wheel will not track behind the front wheel. Spokes are tensioned just like other fasteners.
Spoke tension is best measured using a tool called a spoke tension meter tensiometer such as the Park Tool TM-1 bike spoke tension gauge, which flexes the spoke using a calibrated spring. The procedure described here emphasizes lateral true, which most affects the caliper brake. The idea is to get the wheels true enough to avoid hitting the brake pads. Bike spoke tension gauge other aspects of truing such as radial, centering and tension are important.
For the novice mechanic, it is best to begin with lateral true in order for the brakes to work properly. The spoke nipples labeled A, C, and E are on the left side of the rim and come from the left side flange. Spoke nipples B, D, and F are on the right and come from the right side flange. Left side spokes tend to pull the rim toward the left. Their pulling is offset by the pull of spokes on the right. Each nipple effects relatively wide area of the rim. For example, spoke C will pulls mainly adjacent to its location, but will also effect the rim up to and even 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 pointer is useful as a reference.
Kids cycle target wheel-truing stand allows easier and more accurate work.
It is also possible to use anything that can hold the wheel steady as a truing stand, such as the frame. A pointer can be created by using the brake pads. Radial truing and 26 bmx wheels centering are typically not an issue when only minor corrections are made. It can help to remove the tire while truing. If rim touches left side caliper, find closest nipple to center deviation coming from right side of hub flange.
If rim touches right side caliper, find closest nipple to center deviation coming from left side of hub flange. 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 can be moved toward the hub by tightening spokes. Bike spoke tension gauge, sections of rim can move slightly outward by loosening spokes.
News:Choose the right spokes. DO NOT use the straight gauge 2mm or thicker in diameter spoke when building the wheel. Doing so will void the warranty. Straight.
