There are a number of reasons why your wheels may come out of true. The first reason is the rim is overloaded and deformed from a heavy impact or repeated impacts. It is normal to need to true up your wheels from time to time over the life of the wheels!
Answer #1: Tension spokes properly using a spoke tension meter
If you are regularly having to retension your wheels, or find your spokes won't stay tight, this could be due to the starting tension being too low (we recommend 110-130kgf) or nipples slowly loosening each time the spoke detensions slightly when it's facing towards the ground while you are riding.
TIP: Measuring spoke tension as you tighten the spokes is critical. If you plan to do the work yourself you should invest in a quality spoke tension meter, such as the ones made by Park Tool™️ or DT Swiss™️.
Answer #2: Apply thread-locking compound to spokes before tensioning and trueing
The nipples we spec are precoated with thread-locker. However, repeated truing and/or retensioning can cause this thread-locker to become less effective over time, and potentially result in repeated spoke loosening.
The solution is to bring your wheels up to tension (110-130kgf) and then use a product called Spoke Freeze, made by DT Swiss™️. Drip the Spoke Freeze at the end of the the nipple near the wrench flats where the small gap exists between the spoke and nipple. 1 small drop per nipple and then spin the wheel for a few minutes allowing the centrifugal force to pull the drop outwards toward the threads. Let the compound cure for 24-48 hours before your next ride.
