At What Tension Should Spokes Be Tightened?
There is no definitive answer to this question as it depends on the type of bicycle, the rider's weight, and the riding conditions. Generally speaking, spokes should be tightened to a tension that is high enough to keep the wheel from going out of true (becoming warped), but not so high that the spoke threads start to strip. A good starting point is to tighten the spokes to a tension that is about half of the maximum that the spoke nipple can handle.
