My seat post slipped also on my Hillborne. Part of the frame prep at any bike shop is to take an abrasive round brush and smooth out the inside of the seat tube where the seat stays and top tube have been welded to prevent scratching the seat post.I measured my seat post and it was right on at 27.2. I solved my seat post slippage by wrapping a piece of .010 shim stock ( any auto parts store) around the seat post before inserting it into the seat post. A piece just enough to cover the circumference of the seat post and about 1" wide. It's about as thick as heavy duty aluminum foil.That solved my slippage problem.
