Over the years, the one thing I've not had good success with doing on my own is wheel truing. I've laced up a new wheel build, but had my LBS do the tension / true.

Ok... so, I bring in an older campy hub, mavic ma40 rim, from my back up Trek 560 Pro bike, that I just replaced some spokes on. I mention to the guy @ counter that I'd like a tension and true. He's the newest member of this LBS and hands it to the main mechanic (with whom I've had success with in the past). I watch him work for a about 5min, and he hands the wheel back to me and says 'its done. You've got a very tiny wheel hop, but nothing to be worried about.' (I did know that, and its almost not visible to the naked eye).

The question is: I did not see him tension it. All I saw was a general truing, with a spoke wrench. I did have all the spokes loosened, due to me replacing nearly all the inside spokes, from a chain that shifted to high and cut a lot of them.

Wheel seems to ride fine. Should I worry about no tensioning?

(its on my back up training bike. Only 200 miles on month gets put on it.)
