Why Wheel Maintenance Matters
A wheel that's out of true doesn't just rub your brake pads — loose spokes cause fatigue cracking at the hub flange, broken spokes mid-session, and in worst cases wheel collapse. Catching problems early costs nothing. Ignoring them costs a rim.
Tools You Need
A spoke wrench (match your nipple size — usually 3.4mm for BMX), a truing stand or zip tie on your fork leg as a guide, and patience. A spoke tension meter is nice to have but not essential for basic maintenance.
Checking Spoke Tension
Pluck each spoke like a guitar string. All spokes on the same side should sound roughly the same pitch. A noticeably lower pitch means a loose spoke. A very high pitch could mean overtightened. Squeeze pairs of parallel spokes together — they should have similar resistance.
Truing Laterally
Spin the wheel and watch where it moves toward your guide. If it moves right, tighten spokes on the left side of that section (and optionally loosen spokes on the right). Small adjustments — a quarter turn at a time. Always check tension after adjusting.
Truing Radially
A hop in the wheel (up-down movement) is fixed by adjusting tension in that zone. A high spot — tighten the spokes. A low spot — loosen them. Radial truing is harder to do well; if the wheel has a significant hop, it may have a bent rim.
When to Replace
Replace any cracked rim immediately. Replace a rim that won't stay true despite correct spoke tension. Replace individual broken spokes as soon as they break — riding on 35 spokes transfers load unevenly to the rest.
Summary
Check spoke tension monthly if you ride hard. Catch a loose spoke early and it's a 2-minute fix. Miss it and it's a new wheel.
