Took 5 minutes. LOL. I have to love having wheels that stay true. I have a Park TS-2 truing stand and tension meter but hardly needed either one. The Shimano 7950 24CL wheels have been great. I had to do the usual couple of touch up tension checks in first month but since then, almost a year later, they have stayed right on. I also checked my training powertap rear wheel but it didn't need a thing. I guess it is overbuilt by today's standards with an Open Pro rim, 32 2X 15/16 spokes.
