If I tighten the rear right tire like it should be, there is noticable drag when you give it a spin. Without tires, the driveline is silky smooth and very free. If I tighten it until it binds, then back off just a bit, the tire seldom stays on for an entire race. I've replaced the hex, the pin, the bearings and shimmed behind the pin. I've tried new tires and new lock nuts. I've even painted up the rear carrier, spun the tire and checked to see if it was rubbing. I've swapped tires around and still nothing.

Now that I type this, it just dawned on me that maybe the rear axle is slightly bent?

Anyway, any suggestions where to look or what to try next?

Thanks in advance...
