TNT 2-piece seatpost clamp 1-1/4" or 31.8mm. Used with signs of age and wear, scratches, nicks, tool marks, and the heads of the bolts are worn, the buyer may want to replace the bolts. There was about 4 layers of different colored paint on this when I received it. I buzzed it off with a brass wire wheel on an air tool so there are some tiny marks from that as well but this was smoothed some. Overall not bad looking and could definitely be cleaned up further if desired. Shipping and handling is free in the US.
