First time wheel truing
Just wrapped up my first adventure into wheel truing. I first tried to do it by ear, got no where, and bought a cheap Chinese tension meter. If the included conversion table is accurate, I ended up ~140kgf on the drive side, and ~80kgf on the non-drive side (rear wheel). Does that look right? I know the drive side should be higher, but 75% difference? Also, my other bike (which is identical, but spokes are untouched) measured ~90kgf on the drive side, and ~56kgf on the non-drive side. How much of the difference is because I freshly tightened the spokes on bike#1, whereas bike#2's spokes stretched over the years? Should I lower the tension on bike#1 to match bike#2? How low can I go before I risk the nipples loosening themselves?
