I laced up my 5th (4th successful) last night. first time I didn't have to refer to the web or other wheels to make sure I got the pattern right. I don't have a truing stand so I waited until I got into work this morning and set it up in a spare fork with a dial indicator. I was a bit impressed with myself by how close I was initially. About 15-20 minutes later I had it within +/-.005 in trueness and hop! More than satisfactory for me but I am curious what is an acceptable tolerance for the pros out there?
