How to True a Bicycle Wheel: Complete Step-by-Step Guide
A bicycle wheel doesn’t have to be perfectly straight forever.
Potholes, hard impacts, loose spokes, component settling, and normal use can cause a wheel to develop a side-to-side wobble or become slightly out of round.
The process of correcting these problems is called wheel truing.
Truing a bicycle wheel involves making controlled adjustments to spoke tension so the rim runs straight and round.
With the right tools, patience, and a basic understanding of wheel geometry, many minor wheel-truing problems can be corrected at home.
What Does It Mean to True a Bicycle Wheel?
A properly built bicycle wheel is held together by balanced spoke tension.
When the tension changes in one or more spokes, the rim can move away from its intended position.
Wheel truing involves carefully adjusting spoke nipples to correct those deviations.
There are three primary areas to consider:
- Lateral trueness
- Radial trueness
- Wheel dish
Spoke tension also needs to remain within an appropriate range.
What Is Lateral Wheel Trueness?
Lateral trueness refers to side-to-side movement of the rim.
If you spin the wheel and the rim moves left and right, the wheel has a lateral deviation.
This is the type of wobble most riders notice first.
On a rim-brake bicycle, a significant lateral wobble may even cause the rim to contact the brake pads.
What Is Radial Wheel Trueness?
Radial trueness refers to the roundness of the wheel.
A radial deviation occurs when part of the rim moves closer to or farther away from the hub centerline as the wheel rotates.
This can produce a noticeable hop or dip.
Correcting radial problems is different from correcting a simple side-to-side wobble.
Wheel Dish Is Also Important
A wheel can be laterally true and still be incorrectly positioned relative to the hub.
This is known as an incorrect dish.
The rim should be centered appropriately relative to the hub and the bicycle.

What Tools Do You Need to True a Wheel?
A basic wheel-truing setup may include:
- Wheel truing stand
- Correct-size spoke wrench
- Spoke tension meter
- Dishing gauge
- Appropriate lighting
- A clean work surface
A truing stand makes the process considerably easier, but a minor lateral adjustment can sometimes be made with the wheel installed in the bicycle.
Current wheel-truing guides commonly recommend a truing stand and correctly sized spoke wrench, with a tension meter providing additional control over spoke tension.
Before You Start
Inspect the wheel before making adjustments.
Look for:
- Broken spokes
- Loose spokes
- Damaged nipples
- Cracked rims
- Bent rims
- Hub play
- Obvious impact damage
If the rim is severely bent or damaged, truing may not be the appropriate solution.
A damaged component may need to be replaced.
Step 1: Secure the Wheel
Install the wheel securely in the truing stand.
Make sure the hub is properly seated and that there is no unnecessary movement.
If you’re truing the wheel on the bicycle, make sure the wheel is installed correctly and securely.
Step 2: Find the Lateral Wobble
Slowly rotate the wheel.
Move the truing stand’s indicator close to the rim.
Identify the area where the rim moves toward one side.
Don’t immediately start turning nipples.
First determine the approximate center of the problem and identify which spokes influence that section of the rim.
Step 3: Make Small Adjustments
Wheel truing works best when adjustments are small.
Turn the appropriate nipple by a small increment, then rotate the wheel and check the result.
Avoid making large adjustments.
Small quarter-turn or eighth-turn adjustments give you much better control.
Current wheel-truing guidance similarly emphasizes small adjustments rather than large nipple turns.
Step 4: Understand Which Way to Adjust
Spokes pull the rim toward their respective sides of the hub.
If a section of the rim is too far toward one side, the spoke tension can be adjusted to move the rim back toward the desired position.
The important thing is to understand that you are changing spoke tension—not physically bending the rim into position.
This is why random spoke adjustments can quickly make a wheel worse.
Step 5: Check Radial Trueness
Once the major lateral deviation has been corrected, check the wheel’s radial trueness.
Look for high and low spots as the rim rotates.
Radial adjustments generally involve working with groups of spokes rather than treating the problem as a single-spoke adjustment.
Make small changes and repeatedly check your progress.
Step 6: Check Spoke Tension
A wheel can appear straight while having uneven spoke tension.
Use a spoke tension meter when possible.
Compare the readings around the wheel and make sure the tension remains appropriate for the rim and spokes.
Never increase tension simply to make a wheel appear stronger.
The rim manufacturer’s recommended tension limits should be followed.
Step 7: Stress Relieve the Wheel
Stress relieving allows the spokes and nipples to settle into their intended positions.
A newly built or heavily adjusted wheel may change slightly during this process.
After stress relieving, put the wheel back in the stand and check:
- Lateral trueness
- Radial trueness
- Dish
- Spoke tension
Repeat the process if necessary.
Step 8: Check the Wheel Dish
Use a dishing gauge or another appropriate method to verify that the rim is centered relative to the hub.
This is especially important for rear wheels and other asymmetric wheel designs.
A wheel can look straight in the truing stand but still be incorrectly centered.
How to True a Wheel Without a Truing Stand
For a minor lateral wobble, the bicycle itself can sometimes be used as a reference.
On a rim-brake bicycle, the brake pads can provide a visual or physical reference.
Cable ties attached to the frame or fork can also serve as simple indicators.
However, this approach is less suitable for complicated radial or dish corrections.
A dedicated truing stand provides better control and makes it easier to evaluate small deviations.
Common Wheel-Truing Mistakes
Turning Nipples Too Much
Large adjustments can quickly create new problems.
Make small changes.
Ignoring Spoke Tension
A wheel isn’t properly finished simply because the rim looks straight.
Tension balance matters.
Using the Wrong Spoke Wrench
A poorly fitting wrench can damage spoke nipples.
Forgetting About Dish
A wheel can be true but incorrectly centered.
Trying to Fix a Damaged Rim
A severely bent or cracked rim may need replacement rather than additional truing.
Adjusting Random Spokes
Every spoke influences the rim.
Understand the relationship between spoke tension and rim movement before making adjustments.
When Should You Stop Truing?
Not every wheel needs to be absolutely perfect to be safe and functional.
However, if you encounter:
- A severely bent rim
- Cracked rim material
- Repeatedly loose spokes
- A damaged hub
- A spoke that cannot maintain tension
- Severe tension imbalance
the problem may be more than a simple truing adjustment.
At that point, inspect the wheel carefully before continuing.
Wheel Truing and Spoke Tension Work Together
Truing and spoke tension are closely related.

Shop Wheel-Building Components
Proper wheel maintenance starts with quality components.
WheelBuildingParts.com offers bicycle spokes, bicycle hubs, and bicycle wheel nipples for custom wheel builds and wheel repairs.
Using the correct spoke, nipple, and wheel components makes future maintenance easier and helps ensure the wheel can be properly tensioned and trued.
Final Thoughts
Learning how to true a bicycle wheel is one of the most useful wheel-building and bicycle-maintenance skills you can develop.
The key is patience.
Make small adjustments, understand which spokes affect the rim’s position, monitor spoke tension, and repeatedly check your work.
Don’t confuse trueness with dish, and don’t try to correct serious component damage simply by tightening spokes.
A properly trued wheel is the result of balanced spoke tension, accurate adjustments, and careful attention to the entire wheel system.
