Level of difficulty:
- for talented hobby mechanics
Tool:
- Centring spanner, centring stand, possibly socket spanner or wheel-specific centring tool, centring block
Auxiliary materials:
- Crepe or insulating tape
TIPS:
- Tool:
Use high-quality centring spanners so that the spoke nipples are not damaged. Good spanners surround the nipple on three sides with long surfaces without burrs, and they lie a good distance from the spoke.
- Dial gauge:
A dial gauge from the tool market, which is attached to the centring stand using a magnetic base (from approx. 65 euros), makes work easier. Even better: a centring stand whose clocks display fine deflections magnified by drag pointers.
- Check:
Check the wheel for bearing play. To do this, secure the bike and move the wheel sideways in several places. Slight jerking is an indication of play in the bearings.
- Unbalance:
Tyres can cause slight imbalance. Let the wheel swing out several times in the truing stand until you have determined the heaviest, lowest point. If you mount the spoke magnet of the speedometer opposite the wheel, the wheel will run less unevenly at high speeds.
- Height impacts:
Centring vertical impacts is much more difficult - it is better to leave this to a specialist.
