Among the many issues is that, due to the way it the clamp sides wedge into the mast body, it is VERY DIFFICULT ,if not I mpossible, to get the two sides of the clamp at exactly the same angle! Also, no matter what you do, when you tighten the clamp, the angle of the saddle changes. Compensating for this is also almost impossible because you have to loosen the bolt and tap the wedges out, which almost inevitably results in the clamp sides shifting again. Rinse and repeat, over and over. It's TERRIBLE. A simple two-bolt would have been so much better.

I think there's probably an opportunity for someone like Easton to make a third-party replacement and have commercial success, because pretty much everyone I know with the seat mast hates it and struggles with it.
