2. Visually check the spokes for damage, breakage and corrosion. A broken or bent spoke must be renewed immediately because the load taken by it will be transferred to adjacent spokes which may In turn fall.
3. Tap each spoke lightly with a screwdriver and note the sound produced. Properly tensioned spokes will make a sharp pinging sound, loose ones will produce a lower pitch and over-tight ones will be higher pitched. Unevenly tensioned spokes will promote rim misalignment. Spoke adjustment tools are available, but it is not just a case of slackening tight spokes and tightening loose ones as it is easy to create axial and radial runout in the rim by doing this. It is advisable to seek the help of a wheel building expert.
