The tire and rim had a high point because of runout which I am familiar wiith due to my former employment. The fork end is designed so it has extra space where the axle seats. So I had room to to shim the wheel downward. It is a standard engineering solution for a quick fix. I could buy a new fork but that would be expensive. I have been riding and working on bikes since 1983. I have a 28 on the front and a 25 on the back but when the rear wheel wears I am going to shim that rim down as well to accomodate a 28. I sold my stand and my tools 20 years ago but my diagnostic skills are still sharp. The bike works great and my average speeds are unaffected. The road tortion appears to be better.
