So I get a new WTB Dual Duty 29er Wheelset. The set I have on my Karate Monkey rocks! This one has a major problem, the rear disc will not sit flat on the hub iso mounting surface. Once I torque the bolts down there is a wooble in the disc. It's not the disc because I put it on another hub and it works fine. Has anyone had the same problem? Should I send the wheel back to WTB?

I have never used it.
