Mastering Bicycle Wheel Alignment: A UK Guide

Do you need a wheel alignment gauge? While the term often conjures images of automotive workshops, for the avid cyclist or dedicated home mechanic, a 'wheel alignment gauge' is an absolutely indispensable tool. Specifically, in the world of bicycles, it's known as a wheel centering gauge or a dishing tool. Without one, achieving the precision required for a truly balanced, efficient, and safe ride is incredibly challenging. Proper wheel alignment, or 'dishing', ensures your rim is perfectly centred between the hub's locknuts, a critical factor for optimal performance and brake function.

How to True a Bike Rim: Lateral & Radial Truing

If a bicycle wheel is out-of-true – meaning it's not sufficiently straight or round – it can significantly impact riding performance and shorten the lifespan of your components. Truing is the precise process of using a spoke wrench to adjust spoke tension, thereby improving the wheel’s straightness and roundness.

1. Preliminary Info & Setup

To embark on wheel truing, you’ll need a few essential tools:

• A truing stand, or another method to fixture the wheel and track deviations.
• An appropriately-sized spoke wrench.
• A spoke holder (e.g., CSH-1 or BSH-4) if dealing with bladed spokes.
• Light lubricant (e.g., CL-1.2) and rags.

A bicycle wheel consists of a rim connected to a hub by spokes, which pull the rim from both the right and left sides. Truing involves manipulating the tension of these spokes. There are four basic aspects to wheel truing, though this article will focus on the first two:

1. Lateral Trueness: Correcting side-to-side wobbles as the wheel spins. This is crucial for bikes with rim brakes. Generally, begin by correcting lateral trueness.
2. Radial Trueness: Addressing the wheel’s roundness, or up-and-down movement as it spins. This involves adjusting spoke tension to correct issues of roundness.
3. Dish/Centring: Ensuring the wheel is centred in the frame and aligned with other wheels. (Requires a wheel centering gauge!)
4. Spoke Tension: Ensuring spokes are within an acceptable tightness range. Wheels with highly varied tension won't stay true for long. A spoke tension meter (tensiometer) like the Park Tool TM-1 is best for measuring this.

Wheel truing fundamentally requires three things:

1. A Way To Fixture The Wheel: Holding the wheel steady as it spins. A truing stand is recommended as it isolates problems and speeds up work. If no stand is available, the bike itself can be used, positioned to allow the wheel to spin freely (e.g., in a repair stand or upside down).
2. A Way To Track Deviations: A stationary indicator to pinpoint lateral and radial deviations. Truing stands have built-in indicator fingers. If using the bike, a zip tie attached to the frame can serve as an indicator, moved in or out, up or down.
3. A Way To Adjust Tension: Increasing or decreasing tension by turning the nipple with a spoke wrench. From the outside of the rim, turning the nipple clockwise tightens it, and counter-clockwise loosens it. However, when working from above in a truing stand, it can appear counter-intuitive, as if you're tightening by turning counter-clockwise due to the nipple's perceived orientation.

Other Considerations:

• Tyre Removal: For beginners, removing the tyre can make lateral deviations easier to spot, as the tyre can obscure indicators.
• Lubricant: Keep light lubricant and a rag handy. If nipples are stiff or creaky, apply a drop where the spoke exits the nipple and where the nipple exits the rim.
• Bladed Spokes: To prevent twisting, hold bladed or flat spokes in place with a spoke holder (e.g., BSH-4) while adjusting tension.
• Internal Nipples: If nipples aren't visible at the rim or hub, they're likely internal, located under the rim strip inside the rim, requiring a special tool (e.g., SW-15) for adjustment.

2. Lateral Truing

The truing process involves three steps: locating, isolating, and correcting deviations. Install the wheel in a truing stand (or bicycle frame) and adjust indicators near the outer edge of the rim, not touching.

Locate the Deviation

Spin the wheel and slowly move the indicator towards the rim, observing where it gets close. Continue moving it closer until it lightly contacts the spinning rim. Stop the wheel at this contact point; this is the most severe lateral deviation on that side. At this stage, it doesn't matter if the deviation is on the left or right, as you will correct deviations from both sides to maintain centering.

Isolate the Deviation

Determine where to make the first corrections. If the indicator contacts a long area, find the spoke nearest to the centre of that deviation. Generally, it's preferable to tighten spokes. Choose a spoke originating from the flange on the opposite side of the indicator. For instance, if the rim deviates to the left (touching the left indicator), tighten the spoke coming from the right flange to pull the rim right, away from the indicator. Squeezing spokes can simulate their movement.

Correct the Deviation

Tighten the nipple of the chosen spoke. A 1/4 turn (90 degrees) is a good guideline, up to 1/2 turn (180 degrees) for larger deviations, or 1/8 turn (45 degrees) for minor ones. The key is to make an adjustment and observe the change. Spin the wheel and move the indicator closer in small increments to find the next largest deviation, repeating the process. After three corrections on one side, switch to the opposite indicator. Continue finding and correcting the three largest deviations on each side. As the wheel becomes truer, make smaller corrections.

3. Knowing When to Move On (Lateral Trueness)

How true is true enough? This is subjective. Aim for 0.5 millimetres or less of lateral deviation. Visualise this as about five sheets of typical printing paper. Spin the wheel, adjust the indicator to just touch the rim, then find the largest deviation and compare it to your paper feeler gauge. Continue adjusting if necessary. While perfection is tempting, remember that if you plan to radially true the wheel, you may need to make further lateral adjustments later.

4. Radial Truing

Once laterally true, check for radial trueness. This can be challenging as correcting radial errors can inadvertently introduce lateral ones, requiring back-and-forth adjustments. We look for two main deviations:

• Low Spot: A section of the rim moving inward, towards the hub.
• High Spot: A section of the rim moving away from the hub.

The rim is flexible, so corrections aim to average out its roundness. For radial truing, the left or right edge of the rim sidewall doesn't matter; beginners can use one indicator at a time.

Locate the Deviation (Radial)

Spin the wheel and adjust the indicator below the outer edge of the rim. Slowly move the caliper arm upward until it lightly contacts the spinning rim at a high spot. Back the indicator off to confirm it’s a light rub at the highest point.

Isolate the Deviation (Radial)

Move the rim back and forth through this area to determine where the high spot begins and ends.

Correct the Deviation (Radial)

To correct a high spot, move that section of rim towards the hub by tightening an even number of spokes from both flanges. Spokes pull the rim both laterally and radially. Squeezing both left and right side spokes simultaneously can help visualise the effect. Start by giving each spoke associated with the high spot a half-turn. Spin to verify the high spot is reduced. Repeat: locate, isolate, correct. When correcting radial deviations, tighten spokes evenly in pairs to minimise new lateral deviations, though some are inevitable. Check lateral true every 3-4 radial corrections.

After reducing high spots, low spots might not appear as severe. To address low spots, move the indicator just below the rim. Spin and locate areas with the largest gap between rim and indicator. Isolate the spokes to adjust, similar to high spots, but this time loosen sets of spokes instead of tightening them. Continue this process, checking for lateral errors after every few radial corrections.

5. Knowing When to Stop (Radial Trueness)

The acceptable level of radial trueness is also subjective and influenced by factors like the tyre, which often isn't manufactured to tight tolerances. A general guideline is 1 millimetre or less of radial deviation, roughly equivalent to ten sheets of typical printing paper. Use this as a feeler gauge. If you seek further satisfaction, continue refining, but be aware of diminishing returns.

6. De-Stressing

After numerous nipple adjustments, a wheel often needs 'de-stressing' to allow wound-up spokes to unwind. The safest method is to simply install the wheel on your bike and take it for a ride. Expect some 'pinging' and 'popping' during the first few pedal strokes; this is normal and not a cause for concern.

7. Limitations - Wheel Damage

Not every wheel can be made perfectly true. Damage to wheel components can prevent reliable truing:

• Rim Damage: Impacts from potholes, kerbs, or crashes can deform rims. While minor adjustments might temporarily help, if a rim is badly bent (e.g., if tightening spokes on one side makes no difference because they're already tight, and loosening on the other side is ineffective because they're already loose), it's likely beyond repair by spoke tension adjustment. Such a rim will need replacement, potentially using the old hub if it's in good condition. This complex process is best left to professional mechanics.
• Corroded Nipples: Corrosion and rust in nipple threads will make a wheel impossible to true effectively. Lubricate nipple threads routinely, even if the wheel appears fine, and clean any excess lubricant from braking surfaces.
• Spoke Damage: Bent or mangled spokes are often cosmetic flaws. Spokes are robust; the factory bend is typically the most severe they'll encounter. A single broken spoke can be replaced and the wheel re-trued. However, if a wheel consistently breaks spokes (a good rule of thumb is three broken spokes), it indicates a fundamental issue and should be rebuilt or replaced entirely.

Frequently Asked Questions About Wheel Alignment & Truing

Q1: What's the difference between a wheel alignment gauge and a truing stand?

A wheel alignment gauge (or dishing tool) specifically checks if your wheel's rim is perfectly centred over its hub. A truing stand, on the other hand, is a fixture that holds the wheel, allowing you to identify and correct both side-to-side (lateral) and up-and-down (radial) wobbles in the rim.

Q2: How often should I true my bicycle wheels?

The frequency depends on your riding style and conditions. For casual riders, once a year or if you notice a wobble or brake rub might suffice. Aggressive riders, mountain bikers, or those who hit potholes frequently might need to check their wheels more often, perhaps every few months or after a particularly rough ride.

Q3: Can I true a wheel without a dedicated truing stand?

Yes, you can use your bike frame as a makeshift truing stand. Turn your bike upside down or put it in a repair stand. Use your brake pads or zip ties attached to the frame as indicators. While possible, a dedicated truing stand offers much greater precision, ease, and speed.

Q4: What causes a bicycle wheel to go out of true?

Common causes include hitting potholes, kerbs, or rocks; general wear and tear from riding; spokes losing tension over time; spoke damage; or even a poor initial build. Uneven spoke tension is a primary culprit.

Q5: Is it worth investing in a spoke tension meter?

Absolutely, especially if you're serious about wheel building or truing. While you can true a wheel without one, a tension meter ensures even spoke tension across the wheel, which is critical for wheel strength, durability, and maintaining its true state for longer. Uneven tension can lead to repeated truing needs or even spoke breakages.

Conclusion

Understanding and applying proper wheel alignment and truing techniques are fundamental to bicycle maintenance. A wheel alignment gauge, or dishing tool, ensures your wheel is correctly centred, while a quality truing stand and spoke tension meter provide the precision needed for lateral and radial adjustments. Whether you're a professional mechanic or a dedicated enthusiast, mastering these skills and having the right equipment will significantly enhance your riding experience, offering a smoother, safer, and more efficient journey. Don't underestimate the impact of a perfectly true wheel on your bike's overall performance and longevity.
