Wheel out of true only while being ridden?
My young but 6'-1" tall ridding buddy asked if I could true up his front wheel (29" wheel w/2.6 inch wide mountain tires) on his Schwinn Axum mountain bike. We lifted the bike up and spun the wheel around. It seemed very true (maybe 1 or 2mm lateral) considering the rough treatment he has shown it..He said it was looked more out of true while he was riding it. I'm wondering if this sounds familiar to anyone?
