Welcome to the new and improved Proflex / K2 Tech Forum!
What I do is tighten the pinch bolt on the swingarm on the non allen side until it is locked. Then the bearing assy will stay fixed on your swingarm and the bolt can be torqued to your satisfaction without spinning the inserts. I gave up using a torque wrench as I pretty well know that as tight as you can do by hand is good enough. Then loosen the pinch bolts and retighten them only enough to feel a slight drag on the swiingarm, or it can fall with it's own weight slowly. The crossbolt should be very tight and should only pivot on the bushes.Have fun,Terry
