Now you’ve found the buckle it is time to remedy it. You’ll notice that spokes lead to either side of the hub in an alternative left and right pattern. Spokes on the left hand side will pull the wheel to the left when tightened and Spokes on the right hand side will pull the wheel to the right when tightened. You can loosen spokes to attain the opposite effect.
For example if my wheel was pulling to the disc on the left hand side of my wheel I would want to add tension to the right hand side or none disc spokes and remove tension from the disc brake side spokes.
There are a few pit falls to avoid when you start to true your own wheels. Firstly you shouldn’t add or remove more than a quarter turn of tension on a spoke at once. Adding too much tension to an individual spoke subsequently removes the tension from the surrounding spokes making the over tensioned spoke more likely to fail spectacularly.
When you start to true a wheel count added tension as 1 and count any tension you remove as -1. The idea here is that you try to finish on a number as close to 0 as possible. For example if you add a quarter turn of tension to 3 spokes to pull the wheel to left you should try to remove the tension from opposing spokes. Your spokes don’t have more tension and subsequently they’ll be less likely to fail in the future. (see Fig 2.)
Following these instructions will set you out on a good foundation for truing wheels in the future. As you get used to adding and subtracting tension you can build confidence as to where the tension needs to be adjusted and subsequently true wheels faster and more accurately.
It’s fairly common to hear a pinging noise when you first ride your freshly trued wheel. It’s most common when considerable work has been carried out to straighten or re-tension a wheel. The pinging noise is coming from your spokes. They’re un-twisting themselves. A spoke with a particularly stiff thread or excess tension may twist whilst it’s being adjusted. This pinging may effect the trueness of the wheel and you might need to make further adjustments to the wheel after the all the spokes have un-twisted themselves and the pinging has stopped.
