Easton EC90 Crank Failure

This from Neil, Buttercup's builder and mechanic extraordinaire:

I cleaned and disassembled the left arm and discovered that the outer pinch bolt non threaded hole is under size. The bolt will not pass cleanly through to engage the threaded side. Essentially both sides are threaded and you can torque to spec. without achieving any clamping action. I assume with only 50% clamping force, the arm rocked itself off. It is very evident and is a warranty issue. I don't want to drill it to size.

Simply put, Easton owes me my entrance fee I think. A crank this expensive should not have such an issue. I had a total of maybe 20 miles on it when it failed.
