I finally got around to respacing my new Sm wheels (white bro's excel/talon) I built my own truing stand (out of jackstands... works for now) before I attempted to work on them and read countless articles and threads on how to true a wheel. Eddie, thanks again for offering to help me out. I thought this was a good learning experience for me and being that my training schedule (work) has been delayed lately, I thought this would be the perfect time to sit down and figure out how to do it on my own. Here's the problem I'm having. I used the rotor edge as my primary reference for truing the wheel. I started first with "roundness" then worked on "axial runout." After a few hours, I had the wheel PERFECT (on the rotor side). The sprocket side, on the other hand, was less then perfect. It had a definite imperfection that I could not get out without completely ruining the "trueness" of the other side. The imperfection in the wheel was located directly at the weld seam of the wheel. Is this normal? What are acceptable runout limits? I'm sure if I remounted the tire and never thought about it again, I would never notice it. It just angers me that I can't get the wheels PERFECT! Am I alone here? or could there be a manufacturer flaw in these rims? edit: Here's a video of the wheel untrueness. The other side if nearly PERFECT.
