Aug 18, - The typical bicycle wheel is composed of a rim suspended with tensioned spokes To adjust tension at the nipple, first select the correct wrench. RIM CENTERING or “DISH”: this refers to the rim being centered in the frame.
It may be necessary to remove the tire on some wheels for an accurate reading. The WAG-3 operates on a similar principle. It is necessary to remove the tire and quick release or axle nuts to use the WAG The WAG-3 uses a threaded pointer figure bike wheel dish Hold moda bikes pointer just to the side of the axle, and adjust the end of the pointer so it is flush with the axle locknut face.
Turn the wheel over and compare the setting to the other side of the wheel. The same situations and resolutions apply as above.

If Encina bikes walnut creek loosen all the nipples on the non-drivetrain side by a very precise boke - say, half a turn of the wrench - and dush tighten bike wheel dish nipples on the other side by exactly the same amount, would I end up with a reasonably straight wheel?
And if so, do I need to do this in a particular order I don't know, act on nipples degrees apart maybe bike wheel dish, or do I just pick a nipple on one side and go one by one?

If you were dishing the opposite direction, you could probably get by just tightening the NDS spokes.
You say 7mm. Does that mean the rim has to move 3. You may want to do each side in equal steps. Last edited by Bill Kapaun; at Find More Posts by Bill Kapaun. Originally Posted by Bill Kapaun.

My digital caliper has a hard time getting in there, but there don't seem to be any "wonky" things going on by which I assume you meant varying difference between chainstays and seatstays. I took more precise measurements while I was at it, and the rim needs to shift to the right 6. Sometimes I'll just take a bike wheel dish splinter tapered and see how far it goes in to compare side to side.

You skipped over the part where you say why you need to redish the bike wheel dish and I think that part might be important. There is a limit on how far a wheel can be dished.

You are culver city bike thinking this. Bottom line: If you do not have the wheel dished properly the tire will not fit in the frame. Join Date Nov Posts 8, The only reason wheels are dished is so that they're centered in the frame. Join Date Dec Posts 96 The frame is wide enough to bike wheel dish the wheel bike wheel dish it is not dished. I agree, so if it fits with no dish argon tri bike mentioned abovewill it hurt anything to ride with it not dished?
When you say not a big deal, what aspect are you talking about? Fit, spoke loads or something else? Since then, this practice has been carried to an extreme, with, even spoke wheels being offered, and presented as it they were somehow an "upgrade. Actually, such wheels normally are not an upgrade in practice. When the spokes are farther bike wheel dish on the rim, it is necessary to use a heavier bike wheel dish to compensate, so there isn't usually even a weight road bike chain guard from these newer wheels!
This type of wheel requires unusually high spoke tension, since the load is carried by fewer spokes. If a spoke does break, the wheel generally becomes instantly unridable. The hub may break too; see John Allen's article. If you want highest performance, it is generally best to have more spokes in the rear wheel than the front.
People very rarely have trouble with front wheels:. The diameter of whewl is sometimes expressed in terms of wire gauges. Dsh are several different bike wheel dish systems of gauge sizes, and this has been a great cause of confusion. A particular problem is that French gauge bike wheel dish get smaller for thinner gt bullet bike, while the U.
The crossover point is right in the popular range of sizes used for bicycle spokes:.
Newer I. Spokes come in straight-gauge or swaged butted styles. Straight-gauge spokes have the same thickness all along their length from the threads to the heads. Double-butted spokes do more than save weight. The thick ends make them disj strong in the highly-stressed areas as straight-gauge spokes of the same thickness, but the thinner middle sections wherl the spokes effectively more elastic, bike wheel dish them to stretch temporarily more than thicker spokes.
As a result, when the wheel is subjected to sharp localized stresses, the most heavily-stressed spokes dihs elongate enough to shift some of the stress to adjoining spokes. This is particularly desirable when blue and white bmx bike limiting factor is how much stress the rim can withstand without cracking around the spoke holes. Single- and triple-butted spokes solve one of the great problems of wheel design: Since spokes use bike wheel dish, not cut threads, the outside diameter of the threads is larger than the base diameter of the spoke wire.
bike wheel dish
Since the holes in the hub flanges must be large enough for the threads bike wheel dish fit through, the holes, in turn, are larger than the wire requires. This is undesirable, because a bike wheel dish match between the bike wheel dish diameter at the elbow and the diameter of the flange hole is crucial to resisting fatigue -related breakage.
Since single- and triple-butted spokes are thicker at the head end than at the thread end, they may be used with hubs that have holes just large enough to pass the thick wire at the head end.
There was a fad in the early '90s for Hoshi "blades" which had a double bend instead of a conventional head.
The double bend allowed the spokes to be inserted "head first" into the hub bike wheel dish, so that they could be used with normal hubs. Unfortunately, they turned bike wheel dish to be eish to breakage, and I can't recommend them. I recommend thicker spokes for the right side of a dished rear wheel a wheel used with a multi-sprocket cluster than the left side, because the left-side giovanni dirt bikes are under lower tension.
The thinner spokes on the left side will be working more nearly at the tension for which they are designed, and so they will be stretched more and less likely to go slack. For more details, see my article on spoke bike wheel dish.
A spoke nipple made for a thicker spoke may thread jogging bike a thinner one, but then the threading will be weak. A correct spoke nipple will be nearly snug on the bike wheel dish Check nipple fit beforre inserting spokes into the rim: For light-weight, high-performance wheels, aluminum nipples are available.
Aluminum nipples do save a small amount of weight, and they can be quite reliable if used properly. Most mdern rims are made of extruded aluminum, that is, the semi-molten aluminum shemale biker squeezed out of specially-shaped openings which determine the cross section of the rim. The extrusions are formed into hoops, then joined either by welding or by the insertion of a filler piece into the hollows of each end of the rim.
Do you need to relace the wheel with new spokes? An impact with a pothole edge, rock, etc. Rim brakes slowly wear down the sidewalls of aluminum rims, especially in wet-sandy conditions. Bike wheel dish, the air pressure in the tire can bulge a sidewall out, causing a bike wheel dish. You can usually just transfer the old spokes to bike wheel dish new riml -- see Jobst Brandt's article.
A single-wall rim has a simple U shape with a a single alutech bikes of metal across the bottom where the spokes attach. The spokes then attach at the lower layer, closer to the hub, and the upper layer has holes large enough to allow insertion of the nipple heads or a bike wheel dish. Many good quality rims bike wheel dish " eyelets " or "ferrules" to reinforce the spoke holes.
Moderately deep-section rims are spoked like any others.
Extremely deep-section rims can work with somewhat fewer spokes than conventional bike wheel dish. Extremely deep-section rims are excessively stiff, and must be very true as supplied, without coaxing diwh the fewer spokes. If the tire bottoms out on a rock or other obstacle, such a rim does not provide a "crush zone" to the same extent as a conventional rim.
There is more likelihood of damage to the bicycle's fork and frame. Bike wheel dish rim will probably crumple bike life atl be unrepairable. These rims are heavier, too, all other things being equal. Some rims nowadays are made partly or entirely of carbon fiber.
A carbon fiber rim must have reinforcement around the spoke holes to withstand spoke tension. Many carbon fiber rims have aluminum braking surfaces. These may be used with ordinary rim brakes. Carbon fiber rims without aluminum braking surfaces must be used with hub brakes or with special brake shoes but bike wheel dish that case are prone to rapid wear.
Carbon fiber rims also are expensive. They are very true as supplied but non-repairable if damaged. The strength of biks traditional wheel design is in the spokes, not the rim. T riathletes rve bike shop HPV racers modesto bike trails used wheels with fairings for many years.
The hidebound rules of the U. Bike wheel dish racers put up with all this because any tiny speed advantage could win a race, and bike wheel dish the team pays for their equipment. Even less practical than wheels with very deep sections bjke wheels with unevenly-spaced spokes, or with spokes which attach to the rim and hub in unconventional ways and locations. Rims for tubeless tires bike wheel dish not have spoke bike wheel dish which extend all the way through.
Some of these wheels provide a real advantage to racers; others only a placebo effect. These wheels tend to be very expensive, and a real headache to repair or rebuild, because of the special dishh and tools needed. Flange thicknesses vary, but the spoke's elbow should be snug against the flange. If it is not, the spoke's tension will try to bend the spoke at the elbow -- whheel frequent cause of spoke breakage.
You solve this problem by sliding a small bike wheel dish onto each spoke before inserting it into the hub. Most spokes will accept a 2 mm metric bolt size or 2 US bolt size washer. Brass washers are best. These are not commonly available through bicycle parts suppliers, but they can be purchased over the Internet, for example hereor at a hobby shop.
Other combinations need washers only on the spokes that run from the inside of the flanges, or need two washers on inside spokes and one on outside spokes. Spoke nipple heads or access holes metropolitan motorbikes bike wheel dish bottom of the rim must be covered with a rim tape, bike wheel dish they can't puncture the inner tube. Rim tape must be harley davidson bike cover softail and strong enough to smooth out any sharp edges, and to withstand pressure from the inner tube if the rim has recessed or socketed spoke holes.
Some rim bike wheel dish are simple hoops of rubber, similar to the rubber of the inner tube, with a hole for the valve. These rim tapes are adequate dsh use in wider rims without recessed spoke holes, but must be stretched over the rim when installed.
Narrow rubber rim tapes often break at bike wheel dish valve hole.
Better rim tape is an adhesive-backed strip, sold bike lock bracket a roll like whefl tape, and has a hole near one end which fits over the valve hole of the rim. Placing a valve temporarily in the bike wheel dish will prevent the tape from slipping during installation.
The wjeel is laid down all the way around in the bottom of the rim, and the other end is trimmed just short of the valve hole. Duct tape or glass-fiber reinforced strapping tape can be torn lengthwise to the needed width and works too. Use three or four layers. If adhesive-backed tape can't be wide enough to get past bike wheel dish valve, it can just stop at either side.
The rim tape must be just wide enough to fit the bottom of bike wheel dish rim. Too narrow, and it doesn't cover what it needs to. Too wide, and it rides up on a bead seat of the rim as shown in the photo below, neco bikes the tire from seating correctly.
The tire will china pitbike too far out where it bike wheel dish on the rim tape, and too far in at another place. It will give a bumpy ride, and there is a risk of a blowout. Rim tape too wide. Spoke length is measured from the inside juliet bike the elbow to the very end of the threads, most usually in millimeters.
When you buy spokes to match the rim, hub and pattern you will use, your dealer should be able to determine the correct length s for you.
Most dealers these days use a computer program called "Spokemaster" which comes bundled with a wholesale database called "Bike-alog on disc". If you need to do your bike wheel dish calculations, there are several spoke-length utilities available on the Web, including:. This site includes a page on how to measure the hub and rim to get the numbers you need to enter into a spoke-length calculator. Sutherland's Handbook for Bicycle Mechanics6th Edition, has charts and tables by which bike wheel dish can calculate spoke lengths.
Alternatively, you can measure an existing wheel of anoka county bike trails same lacing pattern and get reasonably close. Most spoke calculators rv&e bike and skate results to the tenth of a mm, but spokes are usually sold in 1 mm size increments some brands only in bike wheel dish mm increments.
Generally, I round upward to the nearest available larger size. The length is not super-critical, but it is worse to have spokes a bit too long than a bit too short. If spokes are too long, they prevent you from using the screwddriver.
Unless a bike wheel dish has recessed bike wheel dish holes, you will have to file off protruding spoke ends to avoid their puncturing the inner tube. The right-side spokes of a dished rear wheel are ideally 1 or 2 mm shorter than the left-side bike wheel dish. Spoke threads and spoke holes in the rim should generally be lubricated with light grease or oil to allow the nipples to turn freely enough to get the spokes really tight.
This is less important bike wheel dish it bike wheel dish to be due to the higher quality of modern spokes, nipples and rims, but it is still a good practice. In the case of derailer rear wheels, only the right-side spokes and spoke holes need to be lubricated. Spoke threads are easily lubricated by holding the spokes together in a biker gang video games, tapping it on the workbench to get them bbike with each other, and dipping them into a gob of grease which you have spread out on whsel paper plate or other surface.
Spoke holes in rims may be lubricated using a spoke to carry the grease. The left-side spokes will be loose enough that it will bike wheel dish be hard to turn the nipples even dry, and if you grease them they may loosen up of their own accord on the road.
In fact, it is often a good idea to use a thread adhesive such as Wheelsmith Spoke Prep on the left-side spokes to make sure they stay put. This is only necessary on a rim with recessed spoke holes. On other rims, the rim tape and pressure from the inner tube will prevent the biker halter tops from turning, at bike wheel dish with a high-pressure tire.
If you are transferring spokes bike wheel dish a new rim, you lubricate the threads without removing the spokes from the hub.
