How to true a dirt bike wheel?
Any kind of impact to your wheel—like hopping off a curb, or hitting a rock or pothole—can knock your rim out of shape. So to keep your bike rolling smoothly and safely, it's important to maintain straight and warp-free wheels by truing them from time to time.

Truing the wheel can be the more daunting task but it's simple enough if you work slowly and methodically. Spin the wheel in your truing stand or frame and see where the rim is out of true.
Correct tension and truing are essential. Both determine the wheel's strength and durability. You should have the wheels and spokes trued and tensioned about once a year (if your ride often). Bicycle spoke rings can be plucked just like any other stringed instrument such as a guitar or a harp.
A bicycle wheel that is properly round and that doesn't wobble from side to side is said to be 'true'. If it's a circle, without high spots or low spots, it's concentrically true. If it the rim doesn't move to one side or the other when you spin it, it's laterally true.
Pro mechanics remove a bent wheel from the bike and put it on a special truing stand, but this is not needed unless you want to get a racing bike in tip-top shape. For a regular bike, you can true it quite nicely without even removing your wheel from your bike.
Wheel truing is the process of using a spoke wrench to change the spoke tension to improve the runout or spinning straightness of the wheel. As a nipple is tightened, it pulls on the spoke. Because the spoke material is somewhat elastic, it will flex slightly and pull against the rim and hub, creating tension.
Although it's possible to accomplish a fast and dirty wheel true without using a dedicated stand, having the right tools definitely makes life much easier.
If the wheel is fixable–it generally looks good but has a wobble–you can expect your local bike shop to charge $20 – $30 to true it using professional equipment like a truing stand for the perfect line and roundness.

At gradients of less than 5%, deeper wheels are definitely faster. And at gradients of greater than 5% — at least at our amateur speeds — lighter wheels will be faster. For this average of 5% and an average speed of 10.5mph, the deeper wheels were slightly faster.
Wheels become out of true if the rim is overloaded and deformed from a heavy impact or repeated impacts. It is normal to need to true up your wheels from time to time over the life of the wheels.
Many would tell you that within 1mm of lateral true is fine, and within 1 to 2mm of radial true is fine. Dish is often regarded as fine so long as it's not problematic. Our standards are a bit tighter than that, and we're generally able to get wheels to about . 15mm of laterally exact true.
It's important to be aware of the most common signs of unbalanced tires, such as a vibrating wheel, uneven tire wear, vehicle pulling to one side, and poor fuel economy. Regular tire balancing and maintenance can prevent symptoms of unbalanced wheels and extend their life for years to come.
Bicycles have a sprocket which is basically a chain driven pulley. A multi speed bike changes speeds by using different size sprockets.
Wheels should be true out of the box, and wheel truing is part of a standard bike tune-up. Unless you suspect something is off or you hit a really big obstacle, you don't need to have your wheels trued more often than your regular tune-up schedule.
Only if you are planning to build wheels or fix a lot of wheels for a profit. Couple zip ties on the frame can do the same job a truing stand can for 90% of home wrenchers. I didn't bother getting a truing stand until I started building wheels. If you are just touching them up, then I don't think it's necessary.
Truing corrects the shape and alignment of the wheel, ensuring it runs true and maintains the desired profile during grinding operations. It is an essential step to optimize grinding performance and achieve precise results.
Truing creates a smooth surface on the wheel periphery, and with no exposed grit the wheel won't cut. Dressing sharpens the wheel by removing bond material and fracturing the superabrasive grit to expose fresh edges, so dressing always follows truing.
Can a wheel not be round?
The Eagle-360 is a concept wheel that is not round, but rather spherical in shape. Goodyear says it is a possible option for autonomous vehicles of the future, allowing the vehicle to move in any direction easily in what would be the ultimate maneuverability.
Do All Four Tires Need To Be Balanced? If there is a vibration issue, all four tires are typically balanced at the same time. The reason is that it's hard to tell which tire is the cause of the vibration. If the repair is done to only one tire, only that tire needs to be re-balanced.
And from a long-term maintenance standpoint, properly tightened spokes will keep your wheel strong and in true for a long time. Checking and tightening your spokes is especially important on a new bike or a new wheel, as the rim, spokes, and hub take time to seat together.
For most folks, too long or two short really doesn't matter as long as it's within about 2 mm, so just round to whichever stock size is closest to ideal. If you go beyond the 2 mm, it is better to be a little short than long.
To make your own house key spoke wrench, simply clamp the key in a vise to hold it so you can cut a nipple-sized slot in it. Don't overtighten the key or you might damage it.
1. the wheel is not dished properly. 2. the frame is out of alignment.
Using a tape measure or string, you can do a full and complete wheel alignment at home. This includes: Castor: the slope of your steering axis, which you can determine by drawing a vertical line through the upper and lower ball joint. Camber: the vertical angle that your tires are tilted, either in or out.
You might think you can ignore a damaged wheel but we would strongly recommend against it. A buckled wheel can affect your suspension, steering, and tyre wear and can cause irreparable damage to these components if not sorted soon enough.
Yes, a buckled alloy wheel can be repaired.
If you can feel the effect of the bend while riding, its too bent to ride safely. Normally bent rim causes bad handling while leaning into a turn. You don't generally feel them on high speed traved because the bent rim is not weighted differently.
What rim depth do pros use?
"Having evaluated many leading brands' wheels and having designing some in my bike-industry career, my recommendation for performance or race-focused consumers would be 40mm-50mm wheels. But, if a consumer is weight conscious, and doesn't like the feel of handling the deeper rim wheels, then 32mm is a good choice."
An optimized tire-rim combo at 36-50mm deep can be more stable than shallow and narrow box section with wide tire. But 80mm deep is just too much to be solve by rim shape.
Generally speaking, wheel weight becomes a part of your vehicle's overall weight. Cars that are heavier will be more difficult to get up to speed, and they're more difficult to slow down when needed. You'll find an impact on your overall fuel consumption, too. There are other considerations you'll want to make though.
Financially, it wouldn't make much sense (unless you build wheels for a living). Also, a well-built wheel should stay MOSTLY true for a VERY long time. However, if you do your own wrenching, you may like having a truing stand. This is especially true if you build your own wheels.
If you can feel the effect of the bend while riding, its too bent to ride safely. Normally bent rim causes bad handling while leaning into a turn. You don't generally feel them on high speed traved because the bent rim is not weighted differently. Another option is to try trying the wheel yourself.
A good, high-quality wheelset can make even the most basic entry-level bike punch above its weight class. By reducing weight, increasing stiffness, improving tire support, and boosting aerodynamics, aftermarket carbon fiber or high-end aluminum wheels will make your bike feel fast and handle better.
How much does it cost to true and balance a set of tires? Zrzavy says that Southwest charges about $64 a set for those tires under 38 inches in diameter, while those over 38 inches cost approximately $120 a set.
They just may have more/less runout than circ*mstances require. A wheel on a beater bike can be considered "true" so long as it's not rubbing. A wheel on a racing bike is not true if there is any measurable runout. One to two millimetres side movement is acceptable.
Hanging a bike up by its wheel is no problem at all. The wheel is designed to take loads far in excess of the weight of the bike. The only potential problem will be if the bike is held upright by the tyre and the tyre goes flat!
Though rims are incredibly sturdy, they do not remain in the same shape forever. A bent rim could cause the tire to leak over time or even a blowout in the worst situation. It is, therefore, necessary that one must have sufficient knowledge about rim so that any risk could be averted beforehand.
How do I know if my spokes are tight enough?
Roger Musson's book "Professional Guide to Wheel Building" simply states that: "The best place to start when judging the correct tension is to examine a similar wheel you know to be good and reliable and compare the spoke tension to the one being built."
While lighter is generally better for speed, especially uphill, it's not the only factor for a bike's performance. Again, riders should also factor in their body weight, personal fitness level, typical terrain, and budget.
A brand new $2500 road bike vs a brand new $1200 bike, both with the same tires, is probably at most 5% faster in general, and 10% faster in its specialty (hills if it is light, flats if it's aero). These percentages are then half as big for the next higher 2x price category and another half again for 4x prices.
At gradients of less than 5%, deeper wheels are definitely faster. And at gradients of greater than 5% — at least at our amateur speeds — lighter wheels will be faster. For this average of 5% and an average speed of 10.5mph, the deeper wheels were slightly faster.
