The Thomson post shown in the photo is 1.245" (31.62mm) The frame measures 1.265" (32.13mm). The seat tube is clearly over by .020" (0.5mm)

The post should fit without an insert. The insert is built into the frame.

This is supposed to be for a standard size 31.6mm seatpost. Is there a standard 31.8mm seatpost? Another thought... Is there a standard 31.8mm reamer? Could the wrong reamer have been used?
