Before adjusting spokes, understanding wheel physics prevents confusion and mistakes.
Basic Wheel Components:
Hub:
- Center of wheel containing bearings - Flanges hold spoke heads - Different drilling patterns (radial, 2x, 3x) - Quick release or thru-axle mounting - Quality affects overall wheel performanceSpokes:
- Connect hub to rim under tension - Usually stainless steel - Straight gauge or butted (variable thickness) - J-bend or straight-pull designs - Length must match exactlyNipples:
- Thread onto spokes at rim - Adjust spoke tension - Brass (durable) or aluminum (light) - External or internal access - Square, hex, or slot driveRim:
- Aluminum or carbon fiber - Single or double wall construction - Rim brake or disc brake specific - Eyeletted or non-eyeletted spoke holes - Width affects tire compatibilityHow Wheels Work:
- All spokes under tension when properly built - Tension creates rigid structure - Load distributed across multiple spokes - Proper tension critical for durability - Balance between all spokes essentialLacing Patterns:
- Radial: Straight from hub to rim, front wheels only - 2-cross: Each spoke crosses two others - 3-cross: Most common, good strength/weight balance - 4-cross: Heavy duty applications - Pattern affects spoke length and wheel strengthIdentifying Wheel Problems
Accurate diagnosis saves time and prevents chasing symptoms instead of causes.
Types of Wheel Issues:
Lateral True (Side-to-Side Wobble):
- Most common issue - Visible wobble when spinning - Caused by uneven spoke tension - Affects brake performance - Usually easiest to fixRadial True (Up-and-Down Hop):
- Wheel not round - Feels like bumping when riding - Often from impact damage - More challenging to correct - May indicate rim damageDish (Centering):
- Wheel not centered in frame - More critical on rear wheels - Caused by uneven side tension - Affects shifting and clearance - Requires systematic approachSpoke Issues:
- Loose spokes: Lose tension over time - Broken spokes: Usually at bend or threads - Frozen nipples: Corrosion prevents adjustment - Stripped nipples: Over-tightening damage - Fatigue cracks: Age and stressDiagnostic Process:
Visual Inspection:
1. Spin wheel slowly 2. Watch gap to brake pad or reference 3. Mark high spots with chalk 4. Note wobble pattern 5. Check for broken spokesFeel Test:
- Squeeze parallel spokes - Compare tension differences - Loose spokes feel soft - Check all around wheel - Note very tight spokes tooSound Test:
- Pluck spokes like guitar strings - Similar tension = similar tone - Dead sound = loose spoke - High ping = very tight - Broken spokes sound deadMeasurement:
- Use dial indicator for precision - Measure runout at multiple points - Document before starting - Set realistic goals - Track improvementStep-by-Step Wheel Truing Process
Systematic approach ensures success. Start with small adjustments and patience.
Lateral (Side-to-Side) Truing:
Step 1: Mount Wheel Securely
- In truing stand or bike frame - Ensure centered and stable - Set reference points close - Remove tire for major work - Note brake pad clearanceStep 2: Identify High Spots
- Spin wheel slowly - Watch for rim moving toward reference - Mark with chalk or tape - Find corresponding spokes - Plan adjustment strategyStep 3: Basic Adjustment Principle
- Tighten spokes pulling toward low side - Loosen spokes on high side - Work in small increments (1/4 turn) - Affect multiple spokes per spot - Balance adjustmentsStep 4: Make Adjustments
- Start at worst spot - Adjust 3-5 spokes in area - Turn nipples from rim side - Right tighty, lefty loosey (from rim view) - Check progress frequentlyStep 5: Work Around Wheel
- Address next worst spot - Maintain overall tension - Don't focus on perfection yet - Get wheel acceptably true - Fine-tune in second passRadial (Up-and-Down) Truing:
More Complex Process:
1. Identify high and low spots 2. Tighten spokes at low spots 3. Loosen at high spots 4. Affects larger spoke groups 5. May need lateral re-adjustmentKey Differences:
- Adjust opposing spokes equally - Maintains lateral true - Smaller adjustments needed - Check for rim damage - May not achieve perfectionDishing (Centering) Wheel:
Process:
1. Measure dish with gauge 2. Determine which side needs adjustment 3. Systematically adjust one side 4. Small adjustments all around 5. Recheck and repeatImportant Notes:
- Rear wheels need more dish - Maintain proper tension - May affect lateral true - Work incrementally - Check frame spacingSpoke Replacement Techniques
Broken spokes require immediate attention to prevent further damage and maintain safety.
Diagnosing Broken Spokes:
- Sudden ping while riding - Wheel immediately goes out of true - Visual inspection confirms break - Usually at J-bend or threads - May damage neighboring spokesGetting Correct Replacement:
- Measure old spoke precisely - Note spoke gauge (thickness) - Match exact length critical - Buy several spares - Quality spokes prevent repeat breaksReplacement Process:
Step 1: Remove Broken Spoke
- Unthread from nipple completely - Remove from hub (may need to remove cassette/rotor) - Note lacing pattern - Keep for measurement - Check neighboring spokesStep 2: Install New Spoke
- Thread through hub correctly - Follow exact lacing pattern - Cross under/over properly - Thread into nipple carefully - Don't force if resistanceStep 3: Initial Tensioning
- Bring to approximate tension - Match neighboring spokes - Don't overtighten initially - Check wheel true - Fine-tune as neededStep 4: Stress Relieving
- Grab parallel spokes - Squeeze firmly together - Works around wheel - Helps spokes seat - Prevents future looseningDrive-Side Considerations:
- May need cassette removal - More difficult access - Higher tension typically - Critical for wheel dish - Take extra careEmergency Repairs:
- Twist broken spoke around neighbor - Open brake to clear wobble - Ride carefully to shop/home - Fix properly ASAP - Carry spare spokesCommon Mistakes to Avoid
Learning from others' errors saves wheels and frustration.
