I finished the build of a new front wheel a couple of weeks ago (my first; a Mavic A719 rim, Campag Centaur hub, DT Swiss competition spokes) and nervously (very nervously!) went out for a ride on it last week. I told the wife to keep her mobile on and beside her just in case. Every bump or click had me looking down to see if the wheel was still round! It was with some relief that I got home and it was still true! Done around 200km on it now so I guess it's going to be ok. Chuffed I am! Like a new dad!!
