Most new seatposts have the clamp bolt pre-greased. But I always check anyway and add grease if there is none. Especially on single-bolt posts, you want that bolt
really tight or it will come loose and ruin the "micro-adjust" ridges on the clamping surfaces. Grease allows getting the bolt tighter without stripping the threads, torque ratings be darned.
