Thanks Rusty but Pats adapter is not technically a "CLAMSHELL" like most others. It is a 3 piece assembly rather than a 2 piece and clamps more like a collet and reduces the chance of torque slippage.
With this and other features (as well as some new upgrades he has in the works) I find his sprocket adapters far superior to other makers adapters. They are the only one I use now.
