I recently bought an old Trek 760 racing bike, that has a front wheel shimmy problem. It is significant enough to cause the front forks to oscillate just a bit, and enough so that I donít dare take my hands off the bars.
The front skewer is tight, the hubs and headset seem to be adjusted OK - no excess slack). The front wheel is straight and true.
The wheels are both 700c X 23, but grossly mismatched, with a V-section clincher rim in the front, and a tubular at the rear. The rear wheel is out of true Ė but I canít seem to get it trued. Nevertheless I do not detect any wobble from the REAR when riding.
I am wondering if this will all go away when I replace the wheel set Ė But meanwhile, is there something else I can check, that I havenít already checked, that could be causing the front end shimmy?
