I recently bought a wheel set with Campy LF hubs and GP4's. I decided to take the Colnago out for a run with the "new" wheel set. It was a great ride but when I removed my hands form the bars, I hand to cant to one side. I checked the dish on the front wheel on a Spin Doctor stand I picked up last year for $25. The delta was about 1/8". The rear was the same. I can't figure out what frame would justify an off set on both wheels unless they were off set left and right! That would be a twisted frame, or would it still be symetrical? The other discouvery was that the tension was way down around 20 or 5/6 on the park tension guage! fixed both problems.
New learning (or reminder, can't remember) for an old guy, just because the parts are quality doesn't mean the workmanship is.
I assume dish implies average offset. Axial variation is another subject.
Even with tubulars mounted with variation of the tread centerline, the average centerline of the tread will be dictated by the off set of the rim.
