Wow, you guys are perfectionists. I true my wheels by tightening up the brakes and finding the spot where the shoes touch.I then back off,and tighten up until the touch is gone-then I'm finished.
Of course this is for older steel rigid MTBs that I ride(or buy/fix/sell()on our crummy, potholed/lifted streets in New Orleans.No point in making them anymore than functional.They will soon be knocked out of true.
Thanks,
