That is if you can find a bike shop that: a) has a qualified wheel builder who, b) knows how to use a tensionometer, and c) has taken the time to contact Velocity to find out what the spoke tension should be on a 48° Dyad rim. This is usually easier said than done and, again, if they aren't familiar with higher spoke count wheelsets commonly found on tandems, going by "feel" or "sound" based on experience gained building 28°, 32°, and 36° single bike wheelsets will get you back to square 1: too much tension for a widely spaced, 48° symetric tandem wheel.
